•
The holding force of the zero-servo is adjusted in b9-01. The holding force will increase if the value of the
setting is increased, but oscillation and hunting will occur if the setting is too large. Adjust b9-01 after
adjusting the speed control gain.
•
The zero-servo detection width is set as the allowable position offset from the zero-servo start position. Set
4 times the number of pulses from the PG.
•
The Zero Servo End signal will go OFF when the zero servo command is turned OFF.
IMPORTANT
Do not lock the servo for extended periods of time at 100% when using the zero servo function. Inverter
errors may result. Extended periods of servo lock can be achieved by ensuring that the current during the ser-
volock is 50% or less or by increasing the Inverter capacity.
