I have programmed a MC024-020 using the PVE-A/H/S and MFOut blocks.
I am driving a PVES valve.
Do I need to worry about dither with this valve?
I have tried to remove dither from the C2P03 output but with no success.
Here are screen captures showing values for configurable variables.
I have tried 3, 5, and 6 for the PinConfig value but still get dither on C2P03.
Thank you in advance for your time and help.

For my application I have 6 analog inputs (C2P01, C2P02, C1P05, C1P10, C1P11, C1P12) corresponding to 6 outputs (C1P03, 04, 05, 06, 07, 08) to drive 6 PVES valves.
I have set in PLUS+1 for each Input and Output values below:
Application.PVE_A_H_S.DigiIn.PinConfig = 2
Application.PVE_A_H_S.DigiIn.PinConfig0 = 2
Application.PVE_A_H_S.Output.PinConfig = 6
Outputs.Group1.CurChgLim = 111
Outputs.Group1.DitherFreq = 0
Outputs.Group1.ReqFreq = 4000
Outputs.C2P03_MFOut1.DitherAmp = 0
I still get dither: 25V amplitude, 2.6kHz frequency and PWM varies with input voltage.
I would like a steady, non-dither output voltage to drive PVES valve.
