3 Mechanical and Electrical Interfacing
The PD28-1-1021 consists of the NEMA11 / 28mm flange size stepper motor QSH2818-32-07-006 with
controller / driver electronics TMCM-1021 mounted on its backside and integrated sensOstep™ encoder. The
PD28-3-1021 uses the longer QSH2818-51-07-012 NEMA11 / 28mm stepper motor together with the same
electronics and encoder.
Please see also stepper motor manuals and TMCM-1021 hardware and firmware manuals for more details.
Note:
In order to make proper use of the integrated sensOstep™ encoder (the sensor IC is placed on the bottom
of the pcb) the TMCM-1021 electronics should not be removed/moved relative to the motor.
In case the integrated encoder feature is not used, the electronics may be moved or even removed from
the motor and placed somewhere else according to application requirements.
