Well that didn't work either .Starting to think that 1 speed maybe just good enough. i even tried hooking up low and high speed to Com but that didn't work either

i may try the diode trick .Any certain size of diode you guys would recommend?

When i wire the 2 speeds the pedal is in off position so that none of the 3 switches are on .When i press the pedal for the first low speed switch nothing happens or press the pedal all the way down to activate the high speed switch nothing happens .If i disconnect one of them the other and...

No even went the pedal is in the off position in the middle where it is not contacting any switches nothing happens when the 2 switches are wired .Think i can live with just one speed and reverse anyways.Tried the tire machine today and it works fine

Well after i thought i had this solved completely i didn't . I only had low speed and reverse connected when i tried it.When i hooked the high speed connection on neither would work.If i disconnected high speed the low speed and reverse would work and the same if i disconnected low speed the...

i ended up using these setting S1, S3, wired together is for low speed S2, S3 wired together is for high speed S4 is for reverse And green wire from switches to COM Used the PLC to program the 2 speeds S3 is the Main FWD Run Terminal Connection S4 is the Reverse Connection P0.01=1 (Remote...

Got it working thanks for all your help

Well i tried the wiring he said .Actually tried ground on com and green back to ground and ran wire from S1 to com .Still didn't work.Even tried all parameters he said.

I was thinking that the green wire should be on COM not on ground where i had it

Very confusing especially for a newbie like me trying to figure out my first VFD. I sent a message to Huanyang Electric asking them for assistance as i can't figure out this manual .Here is what they said.I told them i hooked up the 3 wires for low,high and reverse to S1 S2 S3 and the green...

Don't think i have any PD on this vfd

any idea where i could find the location of that info?

was not set at 1 but still didn't work .Think we have to start from the start again as i have played with settings too many times

Well i got the vfd attached to the tire machine and the motor installed .It operates properly from the keypad . I ran the wires from the switches to the vfd. Now i need some help.I ran the black wire from low speed switch to S1 the brown wire high speed to S2 and the red wire Reverse to S3...

foot pedal lifted activates the reverse micro switch (red and green wire) foot pedal pressed half way activates low speed bottom micro switch (black and green wires) foot pedal depressed all the way down activates high speed upper micro switch (brown and 3 green wires)

Thanks .When i do get there what rpm should i set for low and high speed .I have no idea what the old motor was.Did you hook some type of switch in between the main power and the VFD?

Well bench tested it and got it running fprward and reverse maually.Now on to fun part trying to get the 2 speeds and reverse working for the foot pedal

Just curious but should i have some kind of on/off switch in between power source and VFD and if so what would could i use ?After programming VFD and then shutting power off to it does it keep the settings in memory somehow? Should the main power source ground be hooked to the ground shown at...

Thank you for all the info.Will look into all of this and let you know what i find out

Have manual but doesn't really say anything about where to hook up wires.Will keep reading and maybe ask for support on Huanyang site .I don't think i am at the stage to start to start jumping wires.Will probably fry a new 220 VFD lol
