DMTRWC specifies the temperature rise of the motor winding above motor
case temperature per watt of winding power dissipation between the winding
and case. Motor heatsinking does not affect this value.

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 DMTSCL command scales the torque/force command input. It sets the
full-scale torque/force that will be produced from a 10-volt input command. It
controls the gain applied to the input. This can be used to scale the input to
match application needs. For example, if a torque/force sensor produces 2
volts per Newton-meter, the drive could be scaled to match this by using
DMTSCL5 — this sets 10V = 5 N-m (0.5 N-m/Volt). DMTLIM may limit
torque/force to less than this full-scale value.
Note: To configure the drive in torque/force mode so that a 10-volt
torque/force command produces the rated peak current of the drive (without
reference to motor parameters), enter for DMTSCL the result of the following
