hi every one
am controling the hbs86h driver with s7-1200 plc
the drive have the PEND+/PEND- which indicates that the stepper reached it's target position

when the motor is running with high speed the multimetre reads 24V ,when reaching target position the reading is in mV ,but when i reduce the speed to the lowest value 1mm/s it reads 0.9V 1.2V/1.1V while running.
i haven't connect it to plc yet, does my wiring is wrong, and why i get that voltage drop when reducing the speed
what i want is get a feedback (0v-24v)from the drive indicating that the target position is reached
how i do the wiring
kind regards

Hello,

To wire the HBS86H stepper drive with the S7-1200 PLC to get feedback on the target position, you should connect the PEND+ and PEND - terminals of the drive to a digital input of the PLC. This will provide a voltage signal (0V-24V) when the stepper motor reaches its target position. The voltage drop when reducing speed may be due to the lower current drawn by the motor at slower speeds. Proper wiring and connection to the PLC will ensure accurate feedback signals.
