The DMTAMB command sets the motor ambient temperature used by the
software motor thermal model. The DMTAMB value, in conjunction with the
motor thermal time constant (DMTTCM), the motor winding time constant
(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
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
.
The DMTD command specifies the damping of the motor itself. This includes
both magnetic losses and bearing losses.
