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%.
