MACHINEMATE INC
Low-Cost High-Performance PC-Based CNC Products
The various connections to the MACHINEMATE CNC and its
accessories are described below. MACHINEMATE INC offers a line of CNC models and many common accessories to
enable a complete automation solution from one source. Even though any
particular application might require a different combination of standard and
optional hardware items, MACHINEMATE INC provides the
interface hardware (cables and adapters) to support the integrator bring it all
together.
Standard
CNC Models
The standard MM1,
MM3, MM5, MM7 analog models include an interface to 4 analog servos (using the
4ENC4A MIO, M149) and an interface to a number of 24V discrete input and output
signals (using the 2416 MIO, MM77). These systems are expandable with access to
more servos by adding the 4ENC4A module(s), as needed (up to 32 axes), and with
access to more IO signals by adding the 2416 module(s), as needed.
The standard MM1,
MM3, MM5, MM7 SERCOS models include an interface to 8 digital servos on a
single fiber optic ring (using a SERCOS master in the control) and an interface
to a number of 24V discrete input and output signals (using the internal 2416
connector and an external 2416 MIO, MM77, when more than 24/16 are provided).
These systems are expandable with access to more servos by adding another ring,
as needed (up to 32 axes), and with access to more IO signals by adding the
2416 module(s), as needed. The SERCOS system can also interface to analog
servos by adding the 4ENC4A module(s), as needed (up to 32 axes).
The standard L2
analog models include an interface to 4 analog servos (using the 4AXLX built-in
IO module) and an interface to a number of 24V discrete input and output
signals (using the 2416LX built-in IO module). These systems are expandable
with access to more servos by adding the external 4ENC4A module(s), as needed
(up to 12 axes), and with access to more IO signals by adding the external 2416
module(s), as needed.
The standard L2
SERCOS models include an interface to 8 digital servos (using the built-in
SERCOS master) and an interface to a number of 24V discrete input and output
signals (using the built-in IO connector). These systems are expandable with
access to more servos by adding the external 4ENC4A module(s), as needed (up to
12 axes), and with access to more IO signals by adding the external 2416
module(s), as needed.
The standard eCNC
analog models include an interface to 4 analog servos (using the 4ENC4A MIO,
M149) and an interface to a number of 24V discrete input and output signals
(using the 2416 MIO, MM77). These systems are expandable with access to more
servos by adding the 4ENC4A module(s), as needed (up to 64 axes), and with
access to more IO signals by adding the 2416 module(s), as needed.
The standard eCNC
SERCOS models include an interface to 8 digital servos on a single fiber optic
ring (using a SERCOS master in the control) and an interface to a number of 24V
discrete input and output signals (using the internal 2416 connector and an
external 2416 MIO, MM77, when more than 24/16 are provided). These systems are
expandable with access to more servos by adding another ring, as needed (up to
32 digital axes), and with access to more IO signals by adding the 2416
module(s) as needed. The SERCOS system can also interface to analog servos by
adding the 4ENC4A module(s), as needed (up to 64 axes).
Front panels
For each Windows 2000
CNC model, there are two cables provided between the CNC industrial PC (IPC, in
a CE-rated stainless steel shell) and the operator panel. The first is the
keyboard cable and the second is the VGA cable (IPC has VGA card with standard
VGA 15-pin high-density connector). These cables can be up to 10meters (about
30feet) which is the limit for the VGA signals. This is standard PC technology
and a number of vendors offer a commercially available KVM-extender (keyboard,
video, mouse) that moves these signals via a high-speed Ethernet connection
over very long distances.
For each Windows NT
CNC model, the CNC IPC is mounted directly on the back of the 19” rack-mount
operator panel so no cables are required.
For the touch screen
option (available for either the 12.1” or 15” color displays) for the operator
front panels, there is an additional cable provided to support the touch
screen. It connects the touch screen to the IPC at both the PS/2 mouse
connector and the COM1 serial port.
SERCOS
Built-in IO (24Volt Discrete Inputs and Outputs)
The SERCOS servo
model of the MACHINEMATE CNC offers a
50-pin D-shell connector with 24 24VDC input signals and 16 24VDC output
signals. This connector is pin-compatible with the 50-pin D-shell connectors
for the MTBP models and the Auxiliary panel.
If these discrete IO signals
are required without one of those front panel accessories, then a breakout card
(M314) with a standard 50-pin IO cable (available in many
lengths; MM82 for 2meters) can be obtained from MACHINEMATE INC to convert the
50-pin D-shell connector to terminal strip connections. The discrete wires from
the breakout are connected to the modular IO connectors as needed.
24Volt
Discrete Inputs and Outputs
The connection of the
discrete logic signals from the machine and/or control to the MACHINEMATE CNC is rather
easy. The connections on the 2416 Modular IO (MM77) and on the
2416LX built-in IO module (L2 analog CNC) use pluggable terminal strips (MM80).
Up to eight signal wires are wired to a single 8-pin connector, using a
flat-blade screwdriver and the stripped end of the wires. Five connectors are
provided for the three input bytes and the two output bytes per module.
If other IO bus
technologies such as a field bus (e.g., DeviceNet, Interbus, Profibus, CAN bus)
are used, then the type of connections depend on the hardware being used.
10Volt
Analog Inputs and Outputs
The connection of the
analog signals (from –10VDC to +10VDC) from the machine and/or control to the MACHINEMATE CNC is also
rather easy. The connections on the 4AD4DA Modular IO (M148), the
4ENC4A Modular IO (M149) and on the 4AXLX built-in IO module (L2
analog CNC) use pluggable terminal strips (M183 for 4AD4DA; M181
for 4ENC4A; M186 for 4AXLX). Up to eight wires (for four pairs of
analog signals) are wired to a single 8-pin connector, using a flat-blade
screwdriver and the stripped end of the wires. One connector has 4 channels
(each channel is one signal pair) of either analog inputs or analog outputs; no
signal mixing of inputs and outputs on one connector is allowed.
Relay
Outputs
The connection of the
normally open contacts (for PLC controlled relays) to external electrical
circuits from the MACHINEMATE CNC is also
rather easy. The connections on the 16RO Modular IO (MM72) use
pluggable terminal strips (MM73). Up to eight wires (for four
pairs of wires to each contact) are wired to a single 8-pin connector, using a
flat-blade screwdriver and the stripped end of the wires. Each connector has 4
contacts for 4 relays (each relay has one wire pair for its contact); four
connectors are provided for the 16 relays per module.
Encoder
Feedback Inputs
The connection of the
encoder feedback signals (5VDC differential (TTL square wave) incremental
encoder signals, with two signal pairs for the position feedback (A, /A, B, /B)
and one signal pair for the marker pulse (I, /I) are expected) from the servo
drive and/or motor to the MACHINEMATE CNC is also
rather easy. The connections on the 4ENC4A Modular IO (M149) and
on the 4AXLX built-in IO module (L2 analog CNC) use standard 15-pin D-shell
connectors. MACHINEMATE INC offers a
flying lead cable (M182) with the 15-pin D-shell connector, in a
3-foot length, to make this connection easier. Alternately, a 15-pin D-shell
connector can be pinned and individually wired with commercially available
parts. The flying lead wires are wired to a terminal strip at the drive or to a
nearby terminal strip where the encoder signals from the motor (or drive) are
connected. If the drive has a pinned connector, then the wires can be attached
to the appropriate pins on the appropriate connector for that drive.
Alternately, a cable
(with 15-pin D-shell connectors on both ends; M325) and a
breakout card (M315) can be obtained from MACHINEMATE INC to convert
the 15-pin cable connector to terminal strip connections. The encoder is wired
to the breakout terminal strip.
SERCOS
Drives and their Motors
The connection of the
SERCOS drives (and their motors) to the MACHINEMATE CNC is rather simple, given the SERCOS architecture.
The fiber optic ring
includes a fiber optic cable from the CNC to the first SERCOS drive on the
ring, another cable from one drive to the next (typically very short, when all
drives are mounted adjacent to each other) and a cable from the last drive back
to the CNC. For shorter distances, plastic cables can be used; for longer
distances, glass cables are used (as glass has less effect on the transmission
of the light signal than plastic). Typically these fiber optic cables are
provided by MACHINEMATE INC only with the
drives/motors package, rather than available as a separate part number.
The motor feedback is
wired only to the drive. No connection of the position feedback from the motor
to the CNC is required in a SERCOS system, since the position loop is closed in
the drive and the CNC gets the position information over the SERCOS network.
This SERCOS architecture enables a variety of feedback technologies to be applied
without affecting the CNC (such as an absolute or incremental encoder,
resolver, etc.).
The axis home switch
is wired to the drive; whether this connection is done via terminal strip or
pinned connector depends on the particular drive manufacturer. The axis
overtravel switches are wired to 24V input signals to the CNC (as discrete
input signals, described above).
Analog
Drives and their Motors
The connection of the
analog drives (and their motors) to the MACHINEMATE CNC is described above, with the speed control accomplished
with the 10V analog output connection and the position feedback accomplished
with the encoder feedback input connection.
The axis home switch
and the axis overtravel switches are wired to 24V input signals to the CNC (as
discrete input signals, also described above). Other possible drive signals
(e.g., drive enable and drive fault) are similarly wired as discrete IO
signals.
SERCOS
CNC Status
The SERCOS servo
models of the MACHINEMATE CNC offer a
high-density 15-pin connection for two status indicators, supported by two
hardware relays. The individual relays indicate that 1) the CNC power is valid
and 2) the CNC software is running. These two relay contacts can be wired into
the control’s electrical system as required. Typically, the first (power ok) is
wired into a ‘control on’ circuit while the second (CNC ok) is wired into an
emergency stop circuit. To expedite this connection, a cable (15-pin
high-density to 15-pin D-shell; M323) and a breakout card (M315)
can be obtained from MACHINEMATE INC to convert
the 15-pin high-density cable connector to terminal strip connections.
Alternately, a 15-pin high density connector can be pinned and wired from
commercially available parts. The discrete wires from the breakout are
connected to the electrical system as needed.
Analog
CNC Status
The analog servo
models of the MACHINEMATE CNC offer a
6-pin connection pluggable terminal strip for two status indicators, supported
by two hardware relays. The individual relays indicate that 1) the CNC power is
valid and 2) the CNC software is running. These indicators are the same as for
the SERCOS servo model. These two relay contacts can be wired into the
control’s electrical system as required. Typically, the first (power ok) is
wired into a ‘control on’ circuit while the second (CNC ok) is wired into an
emergency stop circuit. The discrete wires from the pluggable terminal strip
are connected to the electrical system as needed.
MTBP
The MACHINEMATE MTBP (Machine
Tool Builder’s Panel) can make the operator’s panel design and implementation
easier. The MTBP has the common operator switches for many CNC applications.
The MTBP has two sizes to match the corresponding CNC front panel
configurations, either 19” rack mount (M301) or the slim line (M307).
The different layout for the slim line model allows for an additional four
general purpose push buttons (M301 has 8; M307 has
12); each of these push buttons has a programmable LED. Both models are only a
few inches deep, just like the front panels with Windows 2000 based CNC models.
Each model comes with a 2-meter cable.
SERCOS
CNC
When using the SERCOS
CNC, the MTBP’s included 2-meter cable is pin-compatible for an easy
installation. By connecting the cable from the MTBP to the SERCOS control’s
built-in IO connector (and loading the PLC application template for the MTBP
I/O), it takes just a few moments to be running with the MTBP.
Alternately, if the
built-in IO connector is not desired, a breakout card (M302) can
be obtained from MACHINEMATE INC to convert
the 50-pin D-shell connector to terminal strip connections. The discrete wires
from the breakout are connected to the input and output bytes of an IO module.
Analog
CNC
For analog systems, a
breakout card (M302) can be obtained from MACHINEMATE INC to convert
the 50-pin D-shell connector (at the end of the included cable) to terminal
strip connections. The discrete wires from the breakout are connected to the
input and output bytes of an IO module.
Auxiliary
Panel
For the 19”
rack-mount CNC front panel configuration, an Auxiliary Panel is also available.
This panel has the same size as the 19” MTBP but it includes just 16 general
purpose push buttons (each with an LED) and a handwheel (also called a manual
pulse generator or MPG). The handwheel in these Auxiliary Panels comes in
either 5V encoder (M295) or 24VDC input (M293)
models.
A breakout card (M302)
can be obtained from MACHINEMATE INC to convert
the 50-pin D-shell connector (at the end of the included 2-meter cable) to
terminal strip connections. (Alternately, a 50-pin D-shell connector can be
pinned and wired with flying leads from commercially available parts.) The
discrete wires from the breakout are connected to the input and output bytes of
an IO module. If the 5V encoder MPG model is provided rather than the 24VDC
input model, the encoder signals are provided from a terminal strip on the back
of the unit (rather than within the 50-pin connector) to enable an easier
connection as an encoder input (such as the flying lead cable described above (M182)
with the encoder feedback input).
Any of the general
purpose push buttons on an MTBP (on M301, M307, M293,
M295) can be custom engraved for a nominal charge (M305).
Alternately, clear buttons (M304) can be provided to allow the
insertion of a label behind the button.
Handheld
Operator Station
The handheld operator station provides a simple solution to
the requirement for remote operator activities. This rugged pendant includes
the handwheel (in either a 5V encoder model, M316, or a 24V input
model, M300) with several buttons and switches. The cable comes
with its bulkhead connector.
The discrete wires
from the round 26-pin connector are connected to the appropriate input and
output bytes of an IO module. If the 5V encoder handwheel is present, the
flying lead cable (described above with the encoder feedback input) can be
used.
Handwheels
A standalone
handwheel is also available, rather than within a handheld station. The
handwheel is in either a 5V encoder model (M317) or a 24V
input model (M318).
Power
supplies
Power supplies with a DIN-rail mounting are also available. The 5VDC supply (for encoders, M328) is rated for more than 1ampere while the 24VDC supply (for discrete IO, M327) is rated for 3.2amperes.
Miscellaneous
Buttons and Switches
The CNC operator panels have a number of holes predrilled that are covered by the front panel foil. They enable the mounting of operator push buttons on the CNC front panel itself. For some applications with minimal operator button requirements, the buttons could be placed on the front panel avoiding the cost of additional operator panels. Alternately these buttons and switches can be mounted on any operator panel. A 24-position rotary gray-code switch (M165, used for a feedrate override or a spindle speed override) is available, as well as the cycle start and cycle stop push button pair (M166, both can be illuminated) and the jog plus and jog minus push button pair (M167, both can be illuminated). No wires are provided with these switches; they would be individually wired to an IO module as discrete inputs and outputs.
More information is available online about the individual CNC models (Windows 2000 based or Windows NT based) and the particular CNC accessories.
