For the input of the characteristics linearization, the WPC-300 program provides a table and a graphic data input. The input signal is mapped on to the X-axis and the output signal is mapped on to the Y-axis.

Page 25: 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 25 of 43 PAM-199-P-PFN 05.06.2020... -
Page 26: Parameters Of The Power Stage
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 26 of 43 PAM-199-P-PFN 05.06.2020... -
