Hi folks,
I've successfully installed simpler VFD's like Altivar's a few times. I got a good deal on surplus Fuji Frenic Mega VFD's and am trying to install one on my drill press. I have a big step-pulley DP that, because of laziness and access beside the machine, basically lives permanently on the lowest speed. I'm trying to VFD the other DP I have to more easily change speeds for smaller holes.
The Fuji's have many more features and complications than that Altivar's I've worked with, and also more quirks, it seems, haha...
I thought the units were dead until I realized they didn't have a required jumper between P+ and P1. After jumping those, I've at least got data on the panel and can adjust settings. I configured the whole thing for my motor and to use keypad input. In run mode on youtube demo's, you can hold the "up" key to set a base frequency, hit go, and the motor turns. No matter what mode I put mine in, the up key never increases the display from zero. Go doesn't do anything either (predictably, with a frequency of zero).
After that, I thought I might not be understanding the keypad controls correctly, so I change the settings to accept analog freq. control from a pot and a push-button "fwd" button. The control recognizes the input from these (checked in the I/O menu), but still won't actually change the freq. displayed or start the motor when pushing the button.
I read in the manual that some models need the PWM pin shorted to the enable pin (EN), but I can't find an EN pin on mine anywhere, so I assume my model doesn't have it?
It's a FRN1.5G1S-4J. I have the line (400v 3ph) on L1/2/3, the motor on U/V/W, P1 jumped to P+, the pot on 11/12/13, and the fwd button on CM/FWD.
Anyone know the magic trick to coaxing these to work?
