The following will explain the related parameters for gain switching.
(1).
The four parameters, which are servo motor load inertia ratio GD1, position loop
gain value PG1, speed loop gain value VG1, and speed integral gain value VIC,
(PB06~PB09). They are adjusted in the same way as the manual mode
parameters, but its value may be changed during gain switching.
(2).
Gain switch option CDP(PB11)
This parameter is to set the condition of gain switching by changing the lowest digit
of the parameter. It triggers the gain switching by external digital input(DI) signal. Its
external digital input (DI) signal can be set as gain switching function by parameters
PD02~PD09 or PD21~PD24
0 0 0 x
x=0: disable the gain switching.
x=1: activate the gain switching when CDP is ON.
x=2: activate the gain switching when position command frequency is equal to or
higher than CDS setting.
x=3: activate the gain switching when position deviation pulse is equal to or higher
than CDS setting.
x=4: activate the gain switching when motor speed is equal to or higher than CDS
setting.
x=5: activate the gain switching when CDP is OFF.
x=6: activate the gain switching when position command frequency is less than or
equal to CDS setting.
