5.2.5 Gain switching function
By selecting appropriate gain based on internal data or external signal, the following effects can be
obtained.
Decrease the gain at the time of stoppage (servo lock) to reduce vibration.
Increase the gain at the time of stoppage (setting) to shorten the settling time.
Increase the gain during operation to improve command compliance.
Based on condition of the equipment, change the gain with external signal.
Relevant parameters
Set the gain switching function using the following parameters.

Arrange this parameter when performing optimum
adjustment by using the gain switching function.
0: It is fixed to the 1st gain.
1: Enable gain switching of 1st gain (Pr 1.00 to Pr 1.04)
and 2nd gain (Pr 1.05 to Pr 1.09).

For position controlling: When shifting from the 2nd gain to
the 1st gain with Pr 1.15 Position control gain switching
mode set at 3, 5, 6, 7, 8, 9 or 10, set up the delay time from
trigger detection to the switching operation.

For position controlling: Set up triggering level when Pr 1.15
“Position control gain switching mode” is set at 3, 5, 6, 9 or
10. Unit of setting varies with switching mode.
Set the level equal to or higher than the hysteresis.

Mode

For position controlling: Set up triggering hysteresis when
Pr 1.15 “Position control gain switching mode” is set at 3, 5,
6, 9 or 10.
Unit of setting varies with switching mode.
When level < hysteresis, the hysteresis is internally
adjusted so that it is equal to level.

For position controlling: If the difference between Pr 1.00
"1st gain of position loop" and Pr 1.05 "2nd gain of poison
loop" is large, the increasing rate of position loop gain can
be limited by this parameter.
The position loop gain will increase over the time set.
