PB60 Set the model loop gain for when the gain switching is enabled.
PG1B When you set a value less than 1.0 rad/s, the value will be the same as [Pr. PB07].
Model loop This parameter will be enabled only when the following conditions are fulfilled.
gain after gain
switching
Switching during driving may cause a shock. Be sure to switch them after the servo
motor or linear servo motor stops.
Setting range: 0.0 to 2000.0

For example for the servo motor of 3000 r/min rated speed, set 3000 (3s) to increase
speed from 0 r/min to 1000 r/min in 1 s.
Additionally, when 20000 ms or more value is set, it will be clamped to 20000 ms.
Setting range: 0 to 50000
