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 
motor or linear servo motor stops.

Acceleration 
time constant 
  Set the acceleration time required to reach the rated speed from 0 r/min or 0 mm/s 
for VC (Analog speed command) and [Pr. PC05 Internal speed command 1] to [Pr. 
PC11 Internal speed command 7]. 
If the preset speed command is lowe
than the rated speed, acceleration/
deceleration time will be shorter.

For example for the servo motor of 3000 r/min rated speed, set 3000 (3s) to increase 
the speed from 0 r/min to 1000 r/min in 1 second.
