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

kind regards
