gain
switching Set the model loop gain when the gain switching is enabled.
When you set a value less than 1.0 rad/s, the value will be the same as [Pr. PB07].
This parameter will be enabled only when the following conditions are fulfilled.
"Gain adjustment mode selection" in [Pr. PA08] is "Manual mode (_ _ _ 3)".
"Gain switching selection" in [Pr. PB26] is "Input device (gain switching (CDP)) (_
_ _ 1)".
Switching during driving may cause a shock. Be sure to switch them after the servo

time constant This is used to set the acceleration time required to reach the rated speed from 0
r/min in response to VC (Analog speed command) and [Pr. PC05 Internal speed
command 1] to [Pr. PC11 Internal speed command 7].
If the preset speed command is lower
than the rated speed, acceleration/
deceleration time will be shorter.
