5.4 Thermal Behavior

The motor current may be set to the specified maximum current of 3A RMS / 4.2A peak for the TMCM-

1076 which is slightly above the maximum specified current for the stepper motor options (available as

PD57/PD60-x-1076).

Typically, at this nominal current setting the stepper motor and the driver electronics will get hot. Continu-

ous operation at maximum current is not guaranteed without cooling the motor.

Note

Operation with Maximum Current Setting

For table-top testing and applica-

tion bring-up the current should be reduced or the coolStep feature should be

configured to keep heating on a reasonable level. Especially, when there is no

other cooling option for the motor.

For proper and continuous operation at maximum current, the motor flange

must be mounted to the applications mechanical interface with good contact.
