(DMTTCW), the motor thermal resistance (DMTRWC) and the continuous motor
current (DMTIC), is used in a real-time estimation of the motor winding
temperature. When the winding temperature exceeds DMTMAX, the drive
faults and reports E35–Motor Thermal Fault.

Note: This command does not take effect until you cycle power to the drive,
or send the RESET command.
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 DMTD command specifies the damping of the motor itself. This includes
both magnetic losses and bearing losses.

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 EØ–Motor Configuration Error and
E8–Continuous Current = Ø.
