Phase B excitation control signal
Phase A excitation control signal
When the M11 drive signal goes '1',
the pickup motor starts to rotate.
When the M11 drive signal goes '0',
the pickup motor stops.
Description
Supplies 24 V from the no-stacking feeder driver PCB.
Signal (DUPI_OFF) from the DC controller PCB.
See Figure 7-401.
ON/OFF control
Direction control
No error code; however, if a fault in the drive of the motor, a jam will occur.
