Chapter 6 Command Reference - 91 -
The
DMTIC
command sets the continuous operating current for a motor.
Rotary motors: The internal winding temperature will reach 125°C with a
specified heatsink in a 40°C ambient—for Parker motors only.
Linear motors: The winding will reach 90°C in a 25°C ambient—for Parker
motors only.
For heatsink dimensions, see pages
13
,
14
and
15
.
Example
DMTIC5
; Set the motor current to 5 amps rms (equates to
; 7.Ø7 amps peak)

Auto-Setup
: When using a Parker motor and the Aries Support Tool, this
command is automatically set for the selected motor.
If you did not use the Aries Support Tool, are using non-Parker motors, or
sent an
RFS
command to the drive, the parameter is set to zero (0)—you
must
manually set this parameter
to a non-zero number.
For a list of auto-configured commands, see
DMTR
.
The
DMTICD
command sets the current derating percentage at rated speed
(
DMTW
). This value sets the extent to which continuous current must be
reduced at speed to compensate for velocity-related losses in the motor.
For example,
DMTICD3
sets the motor’s continuous current derating to 3%
(or 97% of continuous value
DMTIC
) at the motor’s rated speed (
DMTW
). At
half this speed, it will be reduced 1.5%.
