Precautions on gain switching [A]
• If the gain difference is large at gain switching, and the value in [Pr. PB28 Gain switching time constant] is small, the
machine may operate unexpectedly at gain switching. In this case, increase the value in [Pr. PB28 Gain switching time
constant].
• When the conditions for "Gain switching" and "Gain switching 2" are established at the same time, the servo parameters
after "Gain switching 2" are set as the actual gain to be used.

Setting method for gain switching
When using the gain switching, set the parameters as follows.

Description
Select the switching condition.
[kpulse/s]/
Set the condition values to switch the original gain to the gain for
[pulse]/
"Gain switching".
[r/min]
[ms]
Set the filter time constant for the original gain to be switched to the
gain for "Gain switching".
[kpulse/s]/
Set the condition values to switch the gain to the gain for "Gain
[pulse]/
switching 2".
[r/min]
The setting value is to be larger than in [Pr. PB27 Gain switching
condition].
When this setting value is "0", the gain is not switched to the gain for
"Gain switching 2".
[ms]
Set the filter time constant for the gain to be switched to the gain for
"Gain switching 2".
