*) Please note: only PDx-140-42-SE and TMCM-140-42-SE with pcb version 1.1 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 PD4-140-42-SE mounted to a metal base plate in order to keep stepper
motor temperature within limits for the motor during test (table 4.1) / 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 longest
available stepper motor which is part of the PD4-140-42-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-140-42-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-140-
42-SE electronic module is mounted separately from the motor.
