CAUTION: If the address is changed via the Profibus, the ”126” remains in the parameter list. The actual address for communicating with the module is still the one which was chosen via the Profibus. Page 19 of 37 PAM-199-P-PDP 05.06.2020... -
Page 20: Sens (Failure Monitoring)
CAUTION: If CC command is used, parameters MIN, MAX and TRIGGER have to be considered. CC and those commands affect each other. Pay attention to that if it is necessary to use both kind of settings at the same time. Page 20 of 37 PAM-199-P-PDP 05.06.2020... -
Page 21: Input Signal Adaption
The first quadrant means the ramp up and the second quadrant means the ramp down time. The ramp time is related to 100 % signal step. The ramp function is adjustable independently for each channel. AA:UP AA:DOWN AB:DOWN AB:UP Page 21 of 37 PAM-199-P-PDP 05.06.2020... -
Page 22: Output Signal Adaption
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 24: 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 24 of 37 PAM-199-P-PDP 05.06.2020... -
Page 25: 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 25 of 37 PAM-199-P-PDP 05.06.2020... -

Page 27: Ppwm (Solenoid Current Controller P Gain)
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. Page 27 of 37 PAM-199-P-PDP 05.06.2020... -
