You adjust the current controller to attain the optimum result, with the position
and speed controller switched off.
The step response shows a light overshoot with a short rise time and settling
time. The settling time t
controller (600 µs):

In MP2400.x, define the current gain at standstill.
Some asynchronous motors run rough at maximum speed:
7 7 7 7
In this case, enter in MP2402.x a current gain greater than that in MP2400.x.
The current gain from MP2402.x is reached at maximum speed. It is
interpolated linearly between standstill and maximum speed.
If you enter the value zero in MP2402, the current gain from MP2400 is in
effect for the entire speed range.
MP2400.0-8 Gain for current controller at standstill for axes 1 to 9
Input:
0.00 to 9 999.00 [V/A]
0: Controller disable
MP2402.0-8 Gain for current controller at maximum speed
for axes 1 to 9
Input:
0.00 to 9 999.99 [V/A]
0: Value from MP2400.x
should be smaller than the cycle time of the speed
off
