The cable routing internally seems reasonable enough, but the feed cable, motor cable, and foot pedal cable (that's the pot) don't appear to be shielded. The VFD is of course just a small brick about 8'ењ†'x4', but it is mounted in a 19'x19'x12' electrical box along with a number of relays, disconnects, contactors, switches and other controls to select speed, direction, and control locale (panel or remote), provide safety interlocks, etc. My best guess is that either the drive is in fact failing, but I think more likely is that the 'custom' controller assembly was poorly designed. It has worked just fine for many years, many shows, many rentals. That shop is still happy to rent it out to the theatre occasionally, but they have no idea, and couldn't care less. Then they were bought by a metal supply shop, who have kept the kit mostly for in-house use (it occasionally runs their bender, or something). Then they started using a rental unit which was custom made, commissioned by another outfit to keep in their rental inventory, they had a lot of entertainment clients which used these kinds of things. For several years the revolve was turned by hand by stage crew. The theatre came into possession of this >enormous<< stage revolve (which half-fills a 53' truck) some years ago, but it didn't come with the motor unit. The whole unit (which contains the VFD) is itself part of a somewhat sketchy rental package. Loose wiring, broken or worn potentometer, etc.

Dunno how it went, I was called in just to look at the revolve controller this afternoon. you are associated with a stage production of swingers? (it is Friday) so they're swinging without a net at the moment! This is of a somewhat time sensitive nature, as the drive/motor is used to operate a revolve in a stage production which is opening very soon. I've sent an email to the local distributor, and they've forwarded it on to their 'tech team', but I don't expect an answer soon.

I've read the relevant parts of the manual and quick start guide, and I'm left with the impression that the associated 'START FAULT' tied to the 'UF' display code should not occur while the drive is in operation, but only when power is applied to the unit.ДЄ review of the most recent fault codes using Parameter 50 (fault history) does >not>are<< listed are 'LF', for 'Low DC Bus Voltage Fault', and F9, which suggests 'Internal Faults: The control board has sensed a problem - consult factory.' The fault seems to clear when a stop command is issued, after an interval of several seconds. When these failures occur, the code 'UF' is show on the display. The drive is operating with speed control via an external voltage, provided by a potentiometer.

begins to drive the motor upon command, but then ceases after a random interval ranging from a few seconds to a few dozen seconds.

fails to drive the attached motor upon command, or.The issue is that occasionally, the unit either: Is there anyone here who has experience with this or a similar VFD? I realise that this should perhaps be in Off Topic instead of General Electronics, but as Off Topic can only be viewed by members (and therefore no Off Topic threads are scraped by Google et al) it would be better here for the benefit of others in the future.

I've been asked to troubleshoot an issue with a motor controller built around a Leeson Speedmaster SM Plus Series Sub-Micro Inverter.
