1.Input signals of A+,A-,B+,B- are two groups of orthogonal pulses. A group consists of opposite signals A+ and A-. B
group consists of opposite signals B+ and B-. Group A and group B are orthogonal respectively. The function is the
same as open collector circuit and push-pull encoder.
2.Input terminal Z+,Z- are zero position signals, which is the pulse signal encoder will give each circle.
3.Input signals U+,U-,V+,U-,W+,W- are PM position detecting signals .The phase difference of the three groups is 120°.
Note：Terminals OA+、OB- are reused as open collector circuit encoder input signals. But the open collector
signals can't be chosen with the differential output signal at the same time.
4.4 Switch Terminals Instruction
There're 8 bits in switch terminal and the switch is used as PG division frequency ratio. Ratio of division frequency is
equal to 2 multiply binary system numbers the switch terminals stand for. Switch ON means invalid, OFF means valid.
Examples are shown as follows：
PG card output
signal frequency
selection terminal
Encoder A differential signal input（push-pull and open collector circuit output both
compatible）
Encoder B differential signal input（push-pull and open collector circuit output both
compatible）
Encoder Z differential signal input（push-pull and open collector circuit output both
compatible）
Encoder U differential signal input（push-pull and open collector circuit output both
compatible）
Encoder V differential signal input（push-pull and open collector circuit output both
compatible）
Encoder W differential signal input（push-pull and open collector circuit output both
compatible）
