Switching trigger in 
speed control   
This parameter specifies the trigger of gain switching in speed control. 
Gain parameters are fixed to the first gain parameters P2.00–
P2.04. 
Gain  parameters  are  fixed  to  the  second  gain  parameters 
P2.05, P2.06, P2.08, and P2.09. 
With gain 
switching input 
The first gain is used if the gain switching input is invalid. 
The second gain is used if the gain switching input is valid. 
When the  first  gain  is  used, if  the  absolute value  in  the  torque 
command exceeds (level + lag) [0.1%], the first gain is switched to 
the second gain. 
When the second gain is used, if the absolute value in the torque 
command does not reach (level − lag) [0.1%] and this state keeps 
in the delay time, the second gain is switched to the first gain. 
When  the  first  gain  is  used,  if  the  absolute value  in  the  speed 
command  exceeds  (level  +  lag)  [10  r/min/s],  the  first  gain  is 
switched to the second gain. 
When the second gain is used, if the absolute value in the speed 
command does not reach (level − lag) [10 r/min/s] and this state 
keeps in the delay time, the second gain is switched to the first gain. 
When  the  first  gain  is  used,  if  the  absolute  value  in  the  speed 
command exceeds (level + lag) [r/min], the first gain is switched to 
the second gain. 
When the second gain is used, if the absolute value in the speed 
command does not reach (level − lag) [r/min] and this state keeps 
in the delay time, the second gain is switched to the first gain. 
Note: This parameter is invalid for position gain, meaning the actual position gain is always the 
first gain. 
 
Switching delay in 
speed control 
In speed control, if P2.27 is in the range of 3–5, the first gain is switched back from the second 
gain. This parameter specifies the time from the triggering to the actual switching.
