SimplIQ Command Reference Manual Introduction
MAN-SIMCR (Ver. 4.5)
1-1
Chapter 1: Introduction
This manual describes, in detail, each software command used to manipulate the SimplIQ
line of digital servo drives. It is an integral part of the SimplIQ documentation set, which
includes:
The Harmonica, Cello and Bassoon Installation Guides, which provides full
instructions for installing a drive
The Composer User Manual, which includes explanations of all the software tools that
are a part of Elmo’s Composer software environment
The SimplIQ Software Manual, which describes the comprehensive software used with
the SimplIQ line of digital servo drives
The following diagram illustrates the hierarchy of SimplIQ documentation.

SimplIQ Software Manual
SimplIQ Command Reference Manual
1.1 Command Specification
Commands for SimplIQ drives may be specified from the following sources:
User program A program loaded to the servo drive via one of the
communication options. After program execution begins, the
program is managed by the drive.
RS-232 Serial, point-to-point, short-range communication. Although this
method is rather slow, RS-232 is very easy to use and
requirements are minimal: a standard PC with serial port and
ASCII terminal software.

CANopen Serial, multi-drop, medium speed and medium-range
communication. This type of communication requires special-
purpose host hardware and software.
This manual describes the SimplIQ commands that can be specified from each of these
sources. Most of the commands are equally available for all three sources. Certain
commands, however, are limited in scope according to type of program or
communication.
All the commands are available to CAN communication in text form through the OS
service, objects 0x1023 and 0x1024. In addition, the numerical set/get commands are
available to CAN users in short PDO form, called the “binary interpreter.” The binary
and the OS SCAN interpreters are described fully in the CANopen Implementation Guide.
CANopen may also be used to manipulate the drive using the object dictionary (OD)
method, which is the native CAN method. This manual does not cover OD manipulations
with CANopen; refer to the “Object Dictionary” section of the CANopen Implementation
Guide for full explanations.
The SimplIQ drive responds to many privileged commands — such as those used by the
Composer setup wizard — that are not documented in this manual.
1.2 Scope
This manual includes the complete list of commands used by SimplIQ servo drives. It
specifies how to use each command, along with added remarks and examples.
The commands are presented in two ways:
A task-related listing
Alphabetically
In the task-related reference, the commands are sorted into groups of related commands.
Each group is presented in a table listing the commands with basic descriptions. The
alphabetical command listing provides a detailed explanation of each command, with
examples and references to the SimplIQ Software Manual when necessary.
This Command Reference Manual does not cover the following topics:
User program keywords, used for writing user programs. These, as well as other
issues of developing, running and debugging user programs, are covered in the
SimplIQ Software Manual.
Interpreter functions and operators. The SimplIQ interpreter allows complex
arithmetic expressions and supports many arithmetic, trigonometric and logical
operators. The syntax for interpreter commands is explained in the “Interpreter
Language” chapter of the SimplIQ Software Manual.

Chapter 3: Alphabetical Listing
This chapter lists all the commands in alphabetical order, along with detailed definitions
and examples of each command.
The description of each command includes the following items:
Purpose: The operation or task of the command
Attributes: The characteristics of the command
Type: One of the following:
A command: An instruction to do something. For example, the BG (Begin Motion)
command starts a new motion profile.
A parameter: A data item that may be used later. For example, the AC
(Acceleration) parameter is required for calculating subsequent motions.
A status report: Get a value, such as the motor speed, a digital input or the reason
for the last motor failure.
The parameters and certain commands have numerical values, as follows:
Integer: A 32-bit long integer
Real: A 32-bit floating point number (IEEE style)
String: A set of printable ASCII characters
Integer variables may have the following attributes:
Bit field: The integer should be understood not as a number but rather as a
combination of binary fields. For example, the IP (Digital Input) command reads
many On/Off switches to the same integer, allocating one bit for each.
Option: A selector that may accept one of several options. For example, the motor
direction may be set to forward or reverse, symbolized by the numbers 0 and 1
respectively.
Source: Defines the “agents” that may use the command, as follows:
RS-232 communication
CANopen communication
User program
The command access rights are not equal for all sources. For example,
CANopen binary interpreter cannot use the string commands listed in
this manual. Another example is the LS (List Program) command that,
of course, cannot be performed from within a program.
SimplIQ Command Reference Manual
MAN-SIMCR (Ver. 4.5)
3-1

Restrictions: The use of certain commands is illegal in certain contexts. The reasons
for this may be:
Safety: For example, it is not safe to change the direction of the feedback while the
motor is running.
Relevance: For example, a torque command cannot be specified in speed control
mode (UM=2); in speed mode, the drive automatically sets the torque.
Consistency: A parameter may be inconsistent with the specification of other
parameters. For example, in point-to-point mode, the position absolute value (PA)
may be no higher than the maximum allowed position reference (VH[3]).
Product grade: Elmo drives come in Standard and Advanced grade (model). When
no product grade restriction is cited, the command is relevant for both grades.
Default values: Default value and storage type.
Volatile variables are reset to their defaults with each power on. Non-
volatile variables can be stored using the SV command. Stored non-
volatile values are read from storage upon power on and can be reset
to their defaults using the RS command.
Range: Range definition: For example, the position command may be
specified in the range [-1,073,741,824…-1,073,741,823]
Unit mode (UM): Defines the function of the drive. The unit modes are:
UM=1 Torque control
UM=2 Speed control
UM=3 Micro-stepping
UM=4 Dual-feedback position control
UM=5 Single-feedback position control
Activation: Specifies when the entered parameter value should be used.
Activation may be:
Immediate As soon as the command is processed
Triggered By another command
For example, the AC (acceleration) parameter should only affect the
next motion, triggered by the BG command.
Examples: Simple examples of the command usage. All examples are given in
RS-232 syntax.

AC - Acceleration
Purpose:
Defines the maximum acceleration in counts/second2. This parameter is used in speed
mode (UM=2) and position control modes (UM=3, 4, 5) in PTP (PA, PR) and jogging (JV)
reference modes.
The AC parameter does not affect the present motion. It is used for planning the next
motion, which is initiated by a BG command.
Note: If AC is smaller than SD, the maximum possible acceleration will be limited
to SD and the value of AC will be ineffective.
Attributes: Type: Parameters, Integer
Source: Program, RS-232, CANopen
Restrictions: None
Default values: 20,000,000 (RS), Non-volatile
Range: Acceleration range
Unit modes: UM=2, 3, 4, 5
Activation: BG for RM=0, MO=1 for RM=1
Typical applications:
1. Define acceleration limits for the motion (UM=2)
2. Plan a profiled motion (UM=3, 4, 5)

AG[N] - Analog Gains Array
Purpose:
Sets the gains for preconditioning analog signals, when RM = 1:
AG[1] sets the gain of analog input #1 when used as a torque command (UM=1, 3).
AG[2] sets the gain of analog input #1 when used as a speed command (UM=2).
When RM = 0, the AG[N] parameters are ignored.
The meaning of the analog gains depends on the unit mode, as shown in the following
table.
Value Description Units
UM=1, 3 One volt at the analog reference input
command controls the motor phase current
of AG[1] amperes.
Ampere/volt
UM=2 One volt at the analog reference input
command controls a speed of AG[2]
counts/second.
Count/second/volt
Table 3-2: Analog Gains - Analog Input #1
Notes:
AG[1]defines motor phase amperes and not RMS amperes.
In stepper mode (UM=3), the two external inputs play different roles: The analog
input voltage sets the motor power while the follow pulse/direction or quadrature
input determines the position.
The polarity of the analog reference signal may be reversed by setting the sign of
the AG[N] parameter accordingly.
