Parker Hannifin
Chapter 6 Command Reference 107
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%.

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. Otherwise, the drive
reports the configuration errors E1–Motor Configuration Error and
E3–Maximum Inductance = Ø, and shuts down the drive.
For a list of automatically configured commands, see DMTR.
The DMTIND command specifies the maximum value of motor inductance.
This usually differs from the nominal nameplate value because actual
inductance is usually position dependent. If the maximum value of motor
inductance is not known, specify the nominal inductance as listed on the
motor’s nameplate.
