ElmoMC SimplIQ Digital Servo Drives-Bell Command Reference - Manual (Page 20)

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]).
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.
