Beauty in The Beast: Webb 5BVK Barn Find/Conversion

You are not going to connect the joystick between the power supply and the controller. The joystick terminals would connect in place of the switch furnished with the controller. We'll get to those connections when you have a controller in your hand.

Had misunderstood the prior post about using my power supply to test - thought you meant with joy stick.
Was amazed by your electrical engineering prowess - that would combine my power supply with the joy stick and reverse polarities!
Alas - joy stick will be replacement for forward backward switch on power supply I've ordered...
Noted.

Rest of the description is clear.
Thank you.
Will report back with results.

Good Sunday morning.
Working on a few items today.
1. Will attempt to wire up VFD
2. Program. Have a few questions... Somewhat overwhelming.
Below is a basic list of 17 parameters.
A few of them seem straight forward enough - but many do not.
Very hard to read my motor parameters sign as well - as it is worn - but best pictures I could get have been posted.
Would welcome any suggested approaches or settings.
Off to start the wiring - can tackle the programing afterwards.
Thanks for any input in advance!

- .00 Speed control model (0-2) 0 is V/F control, 1= Sensorless vector control, 2 = Torque control
- .01 Run Command Source. (0-2) 0 is keypad
- .02 Keypad up/down setting (0-3) 0 is value saved when inverter turned off
- .03 What should my "Max Frequency" be set to? (range 10.00 to 400.00)
- .04 And what should my Upper frequency limit" be? (P0.05 - P0.03)
- .05 Lower Frequency Limit (Output frequency is >or=Upper limits the frequency>or= Lower limit of the frequency (0.00-P0.04) 0.00 Hz default
- .06 Keypad reference frequency (0.00-P0.03) 50.00 Hz default

There are then 3 settings - P07 - P10 that have something to do with frequency. I might as well just take a picture of the book because I can hardly decipher these at all. Inclination - leave everything at default...
- .07 Frequency Command Source (0-7). 7 settings ( 0 is default and makes the prior input (P06) the default.)
- .08 Frequency B Command
- .09 Scale of Frequency B Command
- .10 Frequency Command Selection

-.11 Acceleration Time 0 (.1-3600s)
-.12 Deceleration Time 0 (.1-3600s)
- .13 Inverter running direction (0-3). 3 is "wont run backwards". 1 & 2 are forward and reverse directions.
- .14 Carrier Frequency 1-15 kHz
- .15 AVR function
- .16 Motor Perimeter auto-tuning (0-2) Seems to do the settings for you - but must have no load on it for best results.
- .17 - restore all the parameters... suspect I will be pushing this once or twice.

- .00 Speed control model (0-2) 0 is V/F control, 1= Sensorless vector control, 2 = Torque control

Leave at V/F control for now. You will be setting for SV control later, but let's get it running first.

- .01 Run Command Source. (0-2) 0 is keypad

Leave at keypad for now

- .02 Keypad up/down setting (0-3) 0 is value saved when inverter turned off

Leave at 0 for now

- .03 What should my "Max Frequency" be set to? (range 10.00 to 400.00)

Set to 60Hz

- .04 And what should my Upper frequency limit" be? (P0.05 - P0.03)

Set to 60Hz

- .05 Lower Frequency Limit (Output frequency is >or=Upper limits the frequency>or= Lower limit of the frequency (0.00-P0.04) 0.00 Hz default

Set to 30 Hz

- .06 Keypad reference frequency (0.00-P0.03) 50.00 Hz default

There are then 3 settings - P07 - P10 that have something to do with frequency. I might as well just take a picture of the book because I can hardly decipher these at all. Inclination - leave everything at default...

Set to 60Hz

- .07 Frequency Command Source (0-7). 7 settings ( 0 is default and makes the prior input (P06) the default.)

Leave at 0

- .08 Frequency B Command

Leave at default

- .09 Scale of Frequency B Command

Leave at default

- .10 Frequency Command Selection

Set to keypad

-.11 Acceleration Time 0 (.1-3600s)

set to 5

-.12 Deceleration Time 0 (.1-3600s)

set to 5

- .13 Inverter running direction (0-3). 3 is "wont run backwards". 1 & 2 are forward and reverse directions.

set to For/Rev

- .14 Carrier Frequency 1-15 kHz

Leave at default

- .15 AVR function

Leave at default

- .16 Motor Perimeter auto-tuning (0-2) Seems to do the settings for you - but must have no load on it for best results.

Leave at 0

- .17 - restore all the parameters... suspect I will be pushing this once or twice.

Hopefully you won't need this

You need to locate and set the max output current per the motor data plate amps. This may be expressed as a percentage of the VFD max rated output. Not sure if that VFD is set in amps or percentage. It's be a year or so since I set one of those up.

 

[Charlieman22]

Thanks Jim.
Gracious that's thats helpful as a starting point.

So... here comes one of those questions:
Is current = AMPs?
If my motor plate is stamped 14 or 14.7 amp - the nomenclature is tough to read but I think it is showing decimal places in that right hand column - does that give me 14.7 amps of current?
Here is a picture.

 

[JimDawson]

Read that as 14 amps at 220V, and 7 amps at 440V. That is a dual voltage motor. You will be running at 220 (240) volts, so 14 amps.

 

[Charlieman22]

Ok - we are wired.
It will turn on.
I am about to program.

There are 17 P settings to choose from.
None of them seem to call out max amperage.
Not sure how/where to address the max current.Pictures below if helpful?

 

[JimDawson]

Look at the P2.xx parameters

Your motor is 3.7KW (5* 0.745)
60Hz
60Hz
1800 RPM
220V
14 Amps

 

[Charlieman22]

We're close.
Here are the settings.
One confusing item - P2.07. I was expecting to see 50.00Hz when I went to it. Instead it shows 00.706. Default should ahem been 50.00. Should I set this to 60.00







This is P2.07 at it's default.

 

[JimDawson]

No, leave it at the current value.

Once you have the base parameters set, then you can run the auto tune. Should be done unloaded, but it will work OK with the belt on. I think there is a parameter to auto tune without it trying to move the motor for doing it in the loaded condition.

 

[Charlieman22]

Ok - I went through the no movement auto tune - but it doesn't like it.
Seems to trip the system after a few seconds - its supposed to run for about 2 minutes.
Note: it also doesn't set its mutual inductance and current without out load using this form of autotune - even when it works.
They say I should set that from "experience".
Hahahaha!

So I can't autotune without motion.
Perhaps I will have to pull the motor to do that properly.
In the mean time - I decided it was time to take it for a short spin - and see what we have.

Tower: we have ignition

Picture of the VFD riding piggy back.
I welded up some cross members to I didn't have to drill and re-tap from the prior larger VFD into the castings.
