Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Set the meaning of parameter P0-21. P0-20=0 : Count of A or B-phase pulses before P0-21 is set to quadruplicated frequency (for a 2,500ppr encoder, only this option is available) P0-20=1 : Total count of pulses of phases A and B after P0-21 is set to quadruplicated frequency. Parameter functions: Set the count of output pulses per revolution of the motor.

If P0-20=0, P0-21 shall be set to 7; and if P0- 20=1, P0-21 shall be set to 28. Phase A Phase B
