Overview

Controller Notation

This command reference is a supplement to Galil Motion Control User Manual. For proper controller
operation, consult the Users Manual. This manual describes commands to be used with the following
Galil Motion Controllers: DMC-1000, DMC-1500. Commands are listed in alphabetical order.

Please note that all commands may not be valid for every controller. The following symbol is used to
identify the controllers for which the command is applicable.

DMC-1000 DMC-1500

This symbol is placed at the top right corner of each command description. The DMC-1000 symbol
refers to all controllers from the DMC-1000 series (1-8 axes), the DMC-1500 symbol refers to all
controllers from the DMC-1500 series (1-8 axes). When the corresponding box entry is dark, the
command is not valid for that controller.

Removing Non-Applicable Commands:

Since there may be commands which are not applicable to your controller, you may use the following
table to identify and remove these pages:

Servo and Stepper Motor Notation:

Your motion controller has been designed to work with both servo and stepper type motors.
Installation and system setup will vary depending upon whether the controller will be used with
stepper motors, or servo motors. To make finding the appropriate instructions faster and easier, icons
will be next to any information that applies exclusively to one type o f system. Otherwise, assume that
the instructions apply to all types of systems. The icon legend is shown below.

Command Descriptions

Each executable instruction is listed in the following section in alphabetical order. Below is a
description of the information which is provided for each command.

The two-letter Opcode for each instruction is placed in the upper right corner.

Axes Arguments

Some commands require the user to identify the specific axes to be affected. These commands are
followed by uppercase X,Y,Z, W or A,B,C,D,E,F,G and H. No commas are needed and the order of
axes is not important. Do not insert any spaces prior to any command. For example, STX; AMX is
invalid because there is a space after the semicolon. When no argument is given, the command is
executed for all axes.

Valid XYZW syntax

SH X Servo Here, X only
SH XYW Servo Here, X,Y and W axes
SH XZW Servo Here, X,Z and W axes
SH XYZW Servo Here, X,Y,Z and W axes
SH BCAD Servo Here, A,B,C and D axes (Note: ABCD IS the same as XYZW)
SH ADEG Servo Here, A,D,E and G axes (Note: AD is the same as XW)
SH H Servo Here, H axis only
SH Servo Here, all axes

Parameter Arguments

Some commands require numerical arguments to be specified following the instruction. In the
argument description, these commands are followed by lower case x,y,z,w or a,b,c,d,e,f,g,h where the
lowercase letter represents the value. Values may be specified for any axis separately or any
combination of axes. The argument for each axis is separated by commas. Examples of valid syntax
are listed below.

Valid x,y,z,w syntax

AC x Specify argument for x axis only
AC x,y Specify x and y only
AC x,,z Specify x and z only
AC x,y,z,w Specify x,y,z,w
AC a,b,c,d Specify arguments for a,b,c,d (Note: a,b,c,d are the same as x,y,z,w)
AC ,b,,,e Specify b and e axis only (Note: b and y axis are the same)
AC ,,,e,f Specify e and f (Note: e and z axis are the same)

Where x,y,z,w and a,b,c,d,e,f,g and h are replaced by actual values.

2 • Overview DMC-1000/1500 Command Reference

Direct Command Arguments

An alternative method for specifying data is to set data for individual axes using an axis designator
followed by an equals sign. The * symbol defines data for all axes to be the same. For example:

PRY=1000 Sets Y axis data at 1000
PR*=1000 Sets all axes to 1000

Interrogation

Most commands accept a question mark (?) as an argument. This argument causes the controller to
return parameter information listed in the command description. Type the command followed by a ?
for each axis requested. The syntax format is the same as the parameter arguments described above
except '?' replaces the values.

PR ? The controller will return the PR value for the X axis
PR ,,,? The controller will return the PR value for the W axis
PR ?,?,?,? The controller will return the PR value for the A,B,C and D axes
PR ,,,,,,,? The controller will return the PR value for the H axis

Operand Usage

Most commands have a corresponding operand that can be used for interrogation. The Operand Usage
description provides proper syntax and the value returned by the operand. Operands must be used
inside of valid DMC expressions. For example, to display the value of an operand, the user could use
the command:

MG ‘operand’
All of the command operands begin with the underscore character (_). For example, the value of the

current position on the X axis can be assigned to the variable ‘V’ with the command:
V=_TPX

Usage Description

The Usage description specifies the restrictions on proper command usage. The following provides an
explanation of the command information provided:

"While Moving" states whether or not the command is valid while the controller is performing a
previously defined motion.

"In a program" states whether the command may be used as part of a user-defined program.
"Command Line" states whether the command may be used other than in a user-defined program.
"Can be Interrogated" states whether or not the command can be interrogated by using the ? as a

command argument.
"Used as an Operand" states whether the command has an associated operand.

Default Description

In the command description, the DEFAULT section provides the default values for controller setup
parameters. These parameters can be changed and the new values can be saved in the controller's non­volatile memory by using the command, BN. If the setup parameters are not saved in non-volatile
memory, the default values will automatically reset when the system is reset. A reset occurs when the
power is turned off and on, when the reset button is pushed, or the command, RS, is given.

DMC-1000/1500 Command Reference Overview • 3

When a master reset occurs, the controller will always reset all setup parameters to their default values
and the non-volatile memory is cleared to the factory state. A master reset is executed by the
command, <ctrl R> <ctrl S> <Return> OR

by powering up or resetting the controller with the MRST

jumper or dip switch on.
For example, the command KD is used to set the Derivative Constant for each axis. The default value

for the derivative constant is 64. If this parameter is not set by using the command, KD, the controller
will automatically set this value to 64 for each axis. If the Derivative Constant is changed but not
saved in non-volatile memory, the default value of 64 will be used if the controller is reset or upon
power up of the controller. If this value is set and saved in non-volatile memory, it will be restored
upon reset until a master reset is given to the controller.

The default format describes the format for numerical values which are returned when the command is
interrogated. The format value represents the number of digits before and after the decimal point.

DMC-1000 DMC-1500

AC

FUNCTION: Acceleration
DESCRIPTION:

The Acceleration (AC) command sets the linear acceleration rate of the motors for

independent moves, such as PR, PA and JG. The parameters input will be rounded down
to the nearest factor of 1024. The units are in counts per second squared. The
acceleration rate may be changed during motion. The DC command is used to specify
the deceleration rate.

ARGUMENTS: AC x,y,z,w ACX=x AC a,b,c,d,e,f,g,h where

x,y,z,w are unsigned numbers in the range in the range 1024 to 67107840
"?" returns the acceleration value for the specified axes.

USAGE: DEFAULTS:

While Moving Yes Default Value 25600
In a Program Yes Default Format 8.0
Command Line Yes
Can be Interrogated Yes
Used as an Operand Yes

OPERAND USAGE:

_ACx contains the value of acceleration for the specified axis.

RELATED COMMANDS:

DC Specifies deceleration rate.
FA Feedforward Acceleration
IT Smoothing constant - S-curve

EXAMPLES:

AC 150000,200000,300000,400000 Set X-axis acceleration to 150000, Y-axis to

200000 counts/sec2, the Z-axis to 300000
counts/sec2, and the W-axis to 400000

count/sec2.
AC ?,?,?,? Request the Acceleration
0149504,0199680,0299008,0399360 Return Acceleration

(resolution, 1024)
V=_ACY Assigns the Y acceleration to the variable V

Hint: Specify realistic acceleration rates based on your physical system such as motor torque rating,
loads, and amplifier current rating. Specifying an excessive acceleration will cause large following
error during acceleration and the motor will not follow the commanded profile. The acceleration
feedforward command FA will help minimize the error.

DMC-1000 DMC-1500

AD

FUNCTION: After Distance
DESCRIPTION:

The After Distance (AD) command is a trippoint used to control the timing of events. This

command will hold up the execution of the following command until one of the
following conditions have been met:

1. The commanded motor position crosses the specified relative distance from the start of

the move.

2. The motion profiling on the axis is complete.

3. The commanded motion is in the direction which moves away from the specified

position.

The units of the command are quadrature counts. Only one axis may be specified at a time.

The motion profiler must be on or the trippoint will automatically be satisfied.

Note: AD will be affected when the motion smoothing time constant, IT, is not 1. See IT

command for further information.

ARGUMENTS: AD x or AD,y or AD,,z or AD,,,w ADX=x AD a,b,c,d,e,f,g,h where

x,y,z,w are unsigned integers in the range 0 to 2147483647 decimal.

DMC-100/1500 Command Reference AD • 7

Hint: The AD command is accurate to the number of counts that occur in 2 msec. Multiply your
speed by 2 msec to obtain the maximum position error in counts. Remember AD measures
incremental distance from the start of a move on one axis.

8 • AD DMC-1000/1500 Command Reference

AF

FUNCTION: Analog Feedback
DESCRIPTION::

The Analog Feedback (AF) command is used to set an axis with analog instead of digital

feedback (quadrature or
converter, an input voltage of 10 volts is decoded as a position of 2047 counts and a
voltage of -10 volts corresponds to a position of -2048 counts. An option is available for
16-bits where an input voltage of 10 volts is decoded as a position of 32,768 counts and a
voltage of -10volts corresponds to a position of -32,768 counts.

ARGUMENTS: AF x,y,z,w AFX=x AF a,b,c,d,e,f,g,h where

x,y,z,w are integers
1 = Enables analog feedback

Hint: The AI command actually halts execution of the next line in a program until the specified input
is at the desired logic level. Use the conditional Jump command (JP) or input interrupt (II) if you do
not want the program sequence to halt.

10 • AI DMC-1000/1500 Command Reference

AL

FUNCTION: Arm Latch
DESCRIPTION:

The AL command enables the latching function of the controller. When the position latch is

armed, the main or auxiliary encoder position will be captured upon a low going signal.
Each axis has a position latch and can be activated through the general inputs: Input 1 (X
or A axis), Input 2 (Y or B axis), Input 3 (Z or C axis), Input 4 (W or D axis), Input 5 (E
axis), Input 6 (F axis), Input 7 (G axis). The command RL returns the captured position
for the specified axes. When interrogated the AL command will return a 1 if the latch for
that axis is armed or a zero after the latch has occurred. The CN command will change
the polarity of the latch.

ARGUMENTS: AL XYZW where
X,Y,Z,W specifies the X,Y,Z,W axes.
USAGE: DEFAULTS:

While Moving Yes Default Value 0
In a Program Yes Default Format 1.0

AM

FUNCTION: After Move
DESCRIPTION:

The AM command is a trippoint used to control the timing of events. This command will hold

up execution of the following commands until the current move on the specified axis or
axes is completed. Any combination of axes or a motion sequence may be specified with
the AM command. For example, AM XY waits for motion on both the X and Y axis to
be complete. AM with no parameter specifies that motion on all axes be complete.

ARGUMENTS: AM XYZWS or AM SX SY SZ SW or ( AL ABCDEFGH or AL

SASBSCSDSESFSGSH) where

X,Y,Z,W,S specifies X,Y,Z, or W axis, or sequence. No argument specifies that motion on

all axes is complete.

USAGE: DEFAULTS:

While Moving Yes Default Value 0
In a Program Yes Default Format 1.0
Command Line Yes
Can be Interrogated No
Used as an Operand No

RELATED COMMANDS:

BG _BGx contains a 0 if motion complete

EXAMPLES:

#MOVE Program MOVE
PR 5000,5000,5000,5000 Position relative moves
BG X Start the X-axis
AM X After the move is complete on X,
BG Y Start the Y-axis
AM Y After the move is complete on Y,
BG Z Start the Z-axis
AM Z After the move is complete on Z
BG W Start the W-axis
AM W After the move is complete on W
EN End of Program

Hint: AM is a very important command for controlling the timing between multiple move sequences.
For example, if the X-axis is in the middle of a position relative move (PR) you cannot make a position
absolute move (PAX, BGX) until the first move is complete. Use AMX to halt the program sequences
until the first motion is complete. AM tests for profile completion. Th e actual motor may still be
moving. Another method for testing motion complete is to check for the internal variable, _BGx, being
equal to zero (see “BG”command).

AP

FUNCTION: After Absolute Position
DESCRIPTION:

The After Position (AP) command is a trippoint used to control the timing of events. This

command will hold up the execution of the following command until one of the
following conditions have been met:

1. The actual motor position crosses the specified absolute position.

2. The motion profiling on the axis is complete.

3. The commanded motion is in the direction which moves away from the specified

position.

The units of the command are quadrature counts. Only one axis may be specified at a time.

The motion profiler must be on or the trippoint will automatically be satisfied

ARGUMENTS: APx or AP,y or AP,,z or AP,,,w APX=x AP abcdefgh where

x,y,z,w are signed integers in the range -2147483648 to 2147483647 decimal

BG X Begin move
AP 2000 After passing the position 2000
V1=_TPX Assign V1 X position
MG "Position is", V1= Print Message
ST Stop
EN End of Program

Hint: The accuracy of the AP command is the number of counts that occur in 2 msec. Multiply the
speed by 2 msec to obtain the maximum error. AP tests for absolute position. Use the AD command
to measure incremental distances.

DMC-1000 DMC-1500

AR

FUNCTION: After Relative Distance
DESCRIPTION:

The After Relative (AR) command is a trippoint used to control the timing of events. This

command will hold up the execution of the following command until one of the
following conditions have been met:

1. The commanded motor position crosses the specified relative distance from either the

start of the move or the last AR or AD command.

2. The motion profiling on the axis is complete.

3. The commanded motion is in the direction which moves away from the specified

position.

The units of the command are quadrature counts. Only one axis may be specified at a time.

BL

FUNCTION: Reverse Software Limit
DESCRIPTION:

The BL command sets the reverse software limit. If this limit is exceeding during motion,

motion on that axis will decelerate to a stop. Reverse motion beyond this limit is not
permitted. The reverse limit is activated at X-1, Y-1, Z-1, W-1. To disable the reverse
limit, set X,Y,Z,W to -2147483648. The units are in quadrature counts.

When the reverse software limit is activated, the automatic subroutine #LIMSWI will b e

executed if it is included in the program and a program is executing. See User's Manual,
Automatic Subroutine.

ARGUMENTS: BL x,y,z,w BLX=x BL a,b,c,d,e,f,g,h where

x,y,z,w are signed integers in the range -2147483648 to 2147483647.

-214783648 turns off the reverse limit.

Note: This command may cause the Galil software to issue the following warning "A time-out
occurred while waiting for a response from the controller". This warning is normal and is designed to
warn the user when the controller does not respond to a command within the timeout period. This
occurs because this command takes more time than the default timeout of 1 sec. The timeout can be
changed in the Galil software but this warning does not affect the operation of the controller or
software.

CE

FUNCTION: Configure Encoder
DESCRIPTION:

The CE command configures the encoder to the quadrature type or the pulse and direction

type. It also allows inverting the polarity of the encoders. The configuration applies
independently to the four main axes encoders and the four auxiliary enco ders.

ARGUMENTS: CE x,y,z,w CEX=x CE a,b,c,d,e,f,g,h where

x,y,z,w are integers in the range of 0 to 15. Each integer is the sum of two integers n and m

which configure the main and the auxiliary encoders. The values of m and n are

M = MAIN ENCODER TYPE N = AUXILIARY ENCODER TYPE
0 Normal quadrature 0 Normal quadrature
1 Normal pulse and direction 4 Normal pulse and direction
2 Reversed quadrature 8 Reversed quadrature
3 Reversed pulse and direction 12 Reversed pulse and direction

For example: x = 10 implies m = 2 and n = 8, both encoders are reversed quadrature.
"?" returns the value of the encoder configuration for the specified axes.

USAGE: DEFAULTS:

While Moving Yes Default Value O
In a Program Yes Default Format 2.0
Command Line Yes
Can be Interrogated Yes
Used as an Operand Yes

OPERAND USAGE:
_CEx contains the value of encoder type for the axis specified by ‘x’.
RELATED COMMANDS:

MT Specify motor type

EXAMPLES:

CE 0, 3, 6, 2 Configure encoders
CE ?,?,?,? Interrogate configuration
V = _CEX Assign configuration to a variable

Note: When using pulse and direction encoders, the pulse signal is connected to CHA and the
direction signal is connected to CHB.

CI

FUNCTION: Communication Interrupt

DESCRIPTION:

The CI command configures a program interrupt based on characters received on either Port

1, the MAIN serial port, or Port 2, the AUX serial port. An interrupt causes program
flow to jump to the #COMINT subroutine label. If multiple program threads are used,
the #COMINT subroutine runs in thread 0 and threads 1, 2, and 3 continue to run in the
background without interruption. The characters received on the serial port are stored in
internal variables such as P2CH. See chapter 7 for more detailed information on the
communications interrupt.

ARGUMENTS: CI m,n,o

PARAMETER EXPLANATION

m = 0 Do not interrupt Port 1
m = 1 Interrupt on carriage return character on Port 1
m = 2 Interrupt on any character Port 1
m = -1 Clear interrupt data buffer

n = 0 Do not interrupt Port 2
n = 1 Interrupt on carriage return character on Port 2
n = 2 Interrupt on any character Port 2
n = -1 Clear interrupt data buffer

o = 0 Disable live data mode for Port 1
o = 1 Enable live data mode for Port 1

USAGE: DEFAULTS:

While Moving Yes Default Value ­In a Program Yes Default Format ­Command Line No
Can be Interrogated No
Used as an Operand No

EXAMPLES:

CI 0,1,0 Interrupt on <enter> received on Port 2
CI 0,2,0 Interrupt on a single character received on Port 2
CI 1,2,1 Interrupt on <enter> received on Port 1, interrupt on any character

Note: The third field of the CI command enables or disables live data mode on Port 1. If live data
mode is enabled, then the controller will not respond to commands sent to the main serial port. This
setting is necessary to use the communications interrupt on the main serial port.
