(4) Staple swing motor control
Staple swing motor is a 4-phase (FA-S660)/2-phase (FA-S620) control stepping motor.
By controlling the output of pulse signal A, A*, B, and B*, ON/OFF and the rotating
direction of staple swing motor (M4) are switched. The stapler cover switch (MS2) and
fuse (ICP3/FA-S660) are provided in the power supply circuit to the stapler unit swing
motor (M4). The power supply circuit is opened respectively by the stapler cover switch
(MS2) when the stapler cover is opened or by the fuse (ICP3/FA-S660) when overcurrent
flows to the circuit, to stop staple swing motor (M4).
The stapler home position switch (MS4) is provided in the power supply circuit to the bin
shift motor. When the stapler unit is not at the home position, the switch cuts off the power
supply to the bin shift motor to prevent the collision between bins and stapler.
