b9-01 Zero-servo
gain Used to adjust the strength of
the zero-servo lock.
Note: Enabled when the “zero-
servo command” is set for
the multi-function input.
When the zero-servo
command has been input
and the frequency refer-
ence drops below excita-

Gain
ence dro s below excita-
tion level (b2-01), a posi-
tion control loop is
created and the motor
stops. Increasing the
zero-servo gain in turn in-
creases the strength of
the lock. Increasing it by
too much will cause vibra-
tion.
b9-02
Zero-servo
completion
width
Sets the output width of the
P-lock completion signal.
Note: Enabled when the “zero-
servo completion (end)” is
set for multi-function out-
put. The zero-servo
completion signal is ON
when the current position
is within the range (the
zero servo position

coder) in use.
