Hi All,
I have a Hitachi 2.2KW VFD WJ200-022 driving a Lathe -1.5HP, 1750 rpm 220v.The lathe is almost unusable because it errors out even without load with a one inch stock in chuck 5c collet.
I keep getting Error E05.3/ E05.4 I determined that I need a braking resistor.
From what I have read approx. minimum, 40 Ohm, 400W. I was looking at this 1000W, 100Ohm from Huangyang on amazon (B0791CLF8W)
However, I already have this Metal Oxide Varistor . Can it be used as a braking resistor. Its been gathering dust for years(part of auction win years ago).
Cant find much data on this unit. Except it is 2.5kV MCOV . There is a stamp that says type 20 Metal Oxide.
No idea what Resistance is etc. Will it work? any particular cautions in installation?
MOTOR Nameplate:
1.5HP , 1720RPM , 3 Ph , 3.1A, 208-220V, service factor 1.25
What I have tried.:
I tried V/F mode with motor data. Which improved it a bit , but not much.
I tried autotune SLV. which failed with motor run, but succeeded with motor static. Still Errors out with minor pressure.
I just downloaded the Hitachi software to try and set it up better.
but the usual stuff is already setup.
A044 =03 (from last autotune)
H003=1.1
H004 = 4 poles
Set motor amps B012 = 2.8A to leave some overhead (motor is 3.1A).
Set more parameters after reading posts here, but it gets confusing after a while.
Thanks for your help. Learnt a ton already from previous posts.
