Important note: For the PANdrives™ PD-170, the motor coils, hall sensor signals and encoder signals
are already connected. Nevertheless, in order to connect power supply the upper interface board has
to be removed. Never connect or disconnect the boards while power is switched on!
4.2 Application circuit
The schematic shows a typical application circuit using CAN bus interface. Optionally the unit allows
connection of motor hall sensors and encoder N-channel as well as further digital / analog pins and
different interface options.
