Description: Sets the speed threshold for triggering gain switching.
If the gain switching function is enabled and this condition is select
ed:
- Switch from scaling factor 1 to scaling factor 2 when the actual motor speed is greater than the threshold.
- Switch from scaling factor 2 to scaling factor 1 when the actual motor speed is less than the threshold.

Description: Selects a condition for the switching from PI control to P control under the speed loop.
0: Disabled
1: Torque is higher than a par
ameterizable setting value.
2: Using the digital input signal in c29149.
3: Speed is higher than a parameterizable setting value.
4: Acceleration is higher than a parameterizable setting value.
5: Pulse deviation is higher than a parameterizable setting value.

Note
Onl
y when the autotuning function (p5300=0) and gain switching function(p29130=0) are both disabled, PI/P
switching function can be used.
