(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.
Z phase signal
Twy 1 frequency of A phase or B phase
The same circuit is used
for B–phase signals
(PCB and *PCB) and
(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
