anyone?Still having the same issue

Couple of pics of valves

Well after getting the motor VFD up and running have the last issue hopefully with this . There is a main control valve connected to a pilot valve that then goes to the cylinder that to control the Roboarm up and down .The pilot valve was acting up (or so i assume) as when i hit the main...

Very true .Now on to the next issue with it.Think i will create another post

Just curious but could diodes cause any type of issues to the VFD?

Well i got it working .I went out and changed the parameters and it was still a no go .I unsoldered the diodes and reversed the 2 of them pointing the cathode side towards S1 and S2 .I put the old parameters in and i couldn't believe it i had 2 speeds and reverse .Thank you so much guys for the...

That is correct

Diodes did work but it was the same result

Also having a difficult time finding those 2 DPDT switches to match what i have so that the existing pedal lobes will work on the new switches. The only ones i have found are like $60 for 2 plus shipping and i am not spending that much

These are currently the only parameters i currently have .Which parameters should i be putting in to match what you said to try? P0.01=1 (Remote Control) P5.01=16 (S1 Terminal=Multi-Step Speed 1) P5.02=17 (S2 Terminal=Multi-Step Speed 2) P5.03=1 (Forward RUN) S3Terminal connection P5.04=2...

It's all good .I have checked this several times

Doesn't look like any of those switches would work they are all SPDT

They don't look too expensive like 5 for $12 i guess i would have to run another wire from S3 back to the switch

So i need 2 of those switches and these replace the 2 that are on the foot pedal for high and low that are there now?

yes both speeds work if you disconnect the other

Have the diodes wired correctly and have 24 volts DC could it be a parameter issue?

ok i soldered diode from S1 to S3 with flow going to S3 and soldered another diode from S2 to S3 with current flowing to S3 and still not working if i did this correctly .Only reverse works

Bit confused .Where would i put the 2 diodes

Think i put diodes in wrong place after reading what petebob said i should have put one in between S1 and S3 and another in between S2 and S3 ?
