Table 8.1: General operational ratings of the module
*) Please note: only PDx-113-57/60-SE and TMCM-113-57/60-SE with pcb version 1.2 or newer support specified
max. current over full temperature range. Older / pre-series versions may be limited with regard to
temperature range and / or max. motor current.
**) Test set-up / procedure: PANdrive PD4-113-60-SE mounted to a metal base plate in order to keep stepper
motor temperature within limits for the motor during test (table 4.2) / test inside climate chamber with
approx. 53l volume / no forced air convection during test / test duration at least 30min.
Please note: motor temperature should always be kept below upper limit for the motor - that is, motor /
PANdrive should be mounted to an appropriate metal / cooling plate or frame. Especially, the longer
available stepper motor which are part of the PD4-113-57-SE or PD4-113-60-SE may easily reach 100°C or
above when operated at full current over long time without being mounted to any heat-conducting
structure or forced air convection. In case the TMCM-113-57/60-SE electronic module is mounted close to the
motor as with the PANdrives, the motor might substantially heat up the electronics and limit the maximum
environmental temperature during operation. The unit may be operated at higher environmental
temperatures than specified when the duty cycle of the motor and / or the motor current is reduced or in
case the TMCM-113-57/60-SE electronic module is mounted separately from the motor.
