Page 41: Min (Overlap Compensation)
CAUTION: If the MIN value is set too high, it influences the minimal velocity, which cannot be adjusted any longer. 100% Eingang / Input TRIGGER This dead band is necessary, in order to avoid unrequested activations caused by small variations of the input signal.

Page 42: Min (Overlap Compensation)
This dead band is necessary, in order to avoid unrequested activations caused by small variations of the input signal. If this module is used in a position controls, the TRIGGER value should be reduced (typical: 1…10). Page 42 of 48 PAM-199-P 05.06.2020... -
Page 43: Current (Nominal Output Current)
The DITHER frequency should not be confused with the PWM frequency. In some proportional valve documentations a mistake is done by the definition of the DITHER / PWM frequency. It is recognizable by missing information about the DITHER amplitude. Page 43 of 48 PAM-199-P 05.06.2020... -
