3 Mechanical and Electrical Interfacing

All PD42-x-1240 consist of one out of four available NEMA17 / 42mm stepper motors with 2A RMS rated coil

current with the same TMCM-1240 controller / driver electronics mounted on its backside and integrated

SensOstep

™

encoder. The PD42-1-1240 uses the QSH4218-34-20-022 stepper motor with 0.22Nm holding

torque, the PD42-2-1240 uses the QSH4218-38-20-036 stepper motor with 0.36Nm holding torque, the

PD42-3-1240 uses the QSH4218-47-20-044 stepper motor with 0.44Nm holding torque and the PD42-4-

1240 uses the QSH4218-60-20-070 stepper motor with 0.7Nm holding torque. Please see also stepper

motor manuals and TMCM-1240 hardware and ﬁrmware manuals for more details.

NOTICE

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-1240 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.
