5.6.5 ACC (Auto adaptation of the closed loop current controller)

Command
ACC
Operation mode of the closed loop current control.
ON:
In automatic mode PPWM and IPWM are calculated depending on the preset PWM-frequency.
OFF:
Manual adjustment.

5.6.6 PPWM (Solenoid current controller P gain)

5.6.7 IPWM (Solenoid current controller I gain)

Command
PPWM
IPWM
The PI current controller for the solenoids is parameterized with these commands.
CAUTION: These parameters should not be changed without adequate measurement facilities and
experiences.
Attention, if the parameter ACC is set to ON, these adjustments are done automatically.
If the PWM frequency is < 250 Hz, the dynamic of the current controller has to be decreased.
Typical values are: PPWM = 1... 3 and IPWM = 40... 80.
If the PWM frequency is > 1000 Hz, the default values of PPWM = 7 and IPWM = 40 should be chosen.
