7.3.2 Zero-servo Function
7-20
For example, when a 600 p/r encoder is being used, the number of pulses would be 2,400 p/r after multi-
plying by four.
D
The Zero Servo End signal will go OFF when the zero servo command is turned OFF.
D
Do not lock the servo for extended periods of time at 100% when using the zero servo function. Ex-
tended periods of servo lock can be achieved by ensuring that the current during the servolock is 50%
or less or by increasing the Inverter capacity.

Factor of 4: By counting the rising and
falling edges of phase A
this method has four times
the resolution of the PG.
