(3)Z phase signal input
For the Z phase signal (1 rotation signal), a signal width of more than 1
frequency of the A phase or B phase signals is necessary.

The same circuit is used
for Bphase signals
(PCB and *PCB) and
onerotation signals
(PCZ and *PCZ).

If the separate pulse coder rotates in the opposite direction to that of the
servo motor, reconnect the interface cable of the separate pulse coder as
described below.
