Zero-servo
gain
Adjust the strength of the
zero-servo lock.
Enabled when the “zero-servo
command” is set for the
multi-function input. When
the zero-servo command has
been input and the frequency
reference drop below excita-
tion level (b2-01), a position
control loop is created and the
motor stops. Increasing the
zero-servo gain in turn
increases the strength of the
lock. Increasing it by too
much will cause oscillation.

Zero-servo
completion
width
Sets the output width of the
P-lock completion signal.
Enabled when the “zero-servo
completion (end)” is set for a
multi-function input. The
zero-servo completion signal
is ON when the current posi-
tion is within the range (the
zero-servo po zero-
servo completion width.)
Set the allowable position dis-
placement from the zero-
servo position to 4 times the
pulse rate of the PG (pulse
generator, encoder) in use.
