Using This Manual
This user manual provides information for proper operation of the daughter boards that connect to the
DMC-21x3 controllers. It also includes a small listing of commands that pertain to the daughter
boards. This is a subset of the commands listed in the command reference you received with your
motion controller.
Please note that many examples are written for the DMC-2143 four-axes controller or the DMC-2183
eight axes controller. Users of the DMC-2133 3-axis controller, DMC-2123 2-axes controller or
DMC-2113 1-axis controller should note that the DMC-2133 uses the axes denoted as XYZ, the DMC2123 uses the axes denoted as XY, and the DMC-2113 uses the X-axis only.
Examples for the DMC-2183 denote the axes as A,B,C,D,E,F,G,H. Users of the DMC-2153 5-axes
controller denotes the axes as A,B,C,D,E. DMC-2163 6-axes controller denotes the axes as
A,B,C,D,E,F. DMC-2173, 7-axes controller denotes the axes as A,B,C,D,E,F,G. In other words, the
axes names A,B,C,D may be used interchangeably with X, Y, Z, W.
WARNING: Machinery in motion can be dangerous! It is the responsibility of the user to design
effective error handling and safety protection as part of the machine. Galil shall not be liable or
responsible for any incidental or consequential damages.

Introduction
Galil’s DMC-21x3 series motion controllers connect with daughterboard modules that mount directly
on the motion controller. This eliminates the need for a separate cable between the motion controller
and the amplifier or breakout module. This approach saves the cost of the cable and significantly
reduces the real estate required for the controls within a system.
The DMC-21x3 uses a rugged 96 pin DIN board-to-board connector to interface the daughter boards
with the motion controller. The same controller can be ordered with different modules for different
system requirements. This controller series supports modules ranging from passive breakout modules
to 500W-per-channel brush and brushless servo drives to stepper and microstepper drives. Each
module breaks out the I/O provided by the controller and some of the boards also provide additional
I/O functions such as analog inputs or optoisolation. If you do not find the exact module you are
looking for, please contact Galil at 800-377-6329. We will work closely with you to create a module
that will fit your needs.
DC to DC Option
The DMC-21x3 series controllers can be ordered with an optional DC-to-DC converter so that a single DC
power supply can be used to power the controller (as opposed to the standard 5 V and +/-12 V input). This
can be ordered as either the –DC24 (18-36 VDC range) or –DC48 (36-72 VDC range). With the DC
option, a 4-pin molex power connector is provided for DC supply to controller at J99.

DC to DC Pass Through
When using the DC-to-DC converter in conjunction with the Galil amplifier daughter boards described in
this manual, there is an option to have the DC power supply input shared among both boards, which
alleviates the need to supply power to two connectors. Power is passed through from the amp to the
controller via the “Pass Through” header located at J98 (1-4 axes) or JP14 (5-8 axes) on the controller.
When using the pass through on a 1-4 axis DMC-21x3 controller, DC power must be applied only to the
amplifier’s power connector.
When using the pass through on a 5-8 axis DMC-21x3 controller, DC power must be applied to both
amplifier’s power connectors. Power is passed through to the controller only from the second (axes E-H)
amplifier
The proper DC-to-DC converter must be chosen so that the DC voltage range is compatible with the
amplifier and motor voltage requirements. The J98/JP14 header comes standard, hence the purchaser must
specify if they would not like this header present with –NOJ98.

Introduction
For applications requiring a shunt regulator, Galil offers a small mountable model that can be configured for varying
voltage levels. Two fixed voltage threshold settings are available with jumpers, which can be set at either 33 or 66
volts. Additionally, a user defined voltage threshold can be set by changing a simple resistor. This shunt regulator
operates with hysteresis, where the regulator switches on at the set voltage threshold and switches off at 2 volts
below.
The shunt regulator should be placed in parallel with the power supply as in the figure below, and it should be
mounted to a metal surface using thermal grease to aid in heat transfer. Connections are made to the unit at VS
(voltage supply) and PG (power ground) using either the 4-pin Molex connector or the 8-pin Mate ‘N Lock
connector (AMP# 770579-1).
For a summary of shunt regulator operation, as well as details to help determine if one is required in your system,
please refer to application note #5448 at: (
http://www.galilmc.com/support/appnotes/miscellaneous/note5448.pdf).

Amplifier Enable
The standard configuration of the AMPEN signal is TTL active high. In other words, the AMPEN
signal will be high when the controller expects the amplifier to be enabled. The polarity and the
amplitude can be changed. To change the polarity from active high (5 volts= enable, zero volts =
disable) to active low (zero volts = enable, 5 volts= disable), replace the 7407 IC with a 7406
(U2). Note that many amplifiers designate the enable input as ‘inhibit’.
To change the voltage level of the AMPEN signal, note the state of the resistor pack on the ICM-
20100. When pin 1 of the resistor matches pin 1 of the RP1, the output voltage is 0-5 V. To
change to 12 volts, pull the resistor pack and rotate it so that pin 1 is on the 12 volt side. Pin 1 of
the resistor will be marked with a designator, pin 1 of location RP1 can be determined by the
square through hole on the circuit board denoting pin 1. If you remove the resistor pack, the
output signal is open collector, allowing the user to connect an external supply with voltages up to
24V. Note that any external pull-up resistor should limit the current draw to 10 mA

Configurations for ICM-20105
Amplifier Enable Circuit
The ICM-20105 gives the user a broad range of options with regards to the voltage levels present on the enable
signal. The user can choose between High-Amp-Enable (HAEN), Low-Amp-Enable (LAEN), 5V logic, 12V logic,
external voltage supplies up to 24V, sinking, or sourcing. The tables below illustrate the settings for jumpers,
RPacks, and the socketed optocoupler IC. Refer to Figure 7 for precise physical locations of all components. Note
that the resistor pack located at RPAE1 may be reversed to change the active state of the amplifier enable output.
The polarity of RPAE2 must not be changed; however, a different resistor value may be needed to limit the current
to 6 mA . The default value for RPAE2 is 820 ohms, which works at 5V. When using 24 V, RPAE2 should be
replaced with a 4.7 kΩ resistor pack.

Opto Isolation Settings
The ICM-20105 module allows for opto-isolation on all of the digital inputs and outputs. This
includes the dedicated I/O including limits, homes, and abort. The limits and home are powered
by Limit Switch Common. The digital inputs and the Abort Input are powered by Input Common.
The digital outputs are also optically isolated and are capable of sourcing up to 0.5 A per pin with
a 3 A limit for the group of 8 outputs. The outputs are configured for hi-side drive only. The
supply voltage must be connected to output supply voltage, and the supply return must be
connected to output return.
Input Isolation
Opto isolation of the general purpose inputs and the abort input is used by powering the Input
Common line. The limit switch and home inputs are powered by Limit Switch Common. Shown
below is the circuit diagram for the isolated inputs.

Output Isolation
The high current isolated outputs available through the ICM-20105 are configured for High Side
operation. The outputs are capable of 500 mA per output with a total of 3 A from the group of 8
outputs. The figure below shows the manner in which the load should be connected. The output
will be at the voltage that is supplied to the OUTSUP pin. Up to 30 VDC may be supplied to
OUTSUP.
The RPOUT resistor pack allows configuration of the active state of the outputs. For example
when you issue the SB1 command, the polarity of the resistor will determine whether the output is
turned on or off.
