Motor Power
This signal is an output from the PHC. It is output from a PWM controlled “H” bridge motor drive. The
maximum current level can be set using DIP switches #1 and #2. This output is intended to drive a 24Vdc
permanent magnet motor.
Lifter Brake
This output from the PHC is a 24Vdc signal to an electromagnetic brake. When this signal is energized, the
brake is released to allow lifter motion.
