Multi part question

Has anyone bought ad used an AX2 – B 0.75kW VFD? I have one here and am curious if I by bad luck got a dud or if all VFDs are equally awful from this maker.

Part two

When I wired this VFD in it comes up when turned on with "limit protection" s far as I can tell from using google translate on the chinese only manual. This is separate to Overload or High Voltage protection.

In part due to not being good at VFDs at the best of times and also because I have no usable manual: can anyone think what limit protection is on a VFD? At this point it triggers with or without a motor attached and I have never even got the motor spinning.

Which maker is that then?

The error message might easily be bypassed if we knew what it was and without a readable manual it will be a challenge to set up.

Is the same unit available from other sellers and do any of those have downloadable manual I wonder.

May not have been a good idea to power it up without motor connected….

Motor not connected does not matter.

Some VFD's (alledgedly) do not like the motor being disconnected whilst running, is that what you are thinking of?

Alas had a look at the listing and couldn't find any maker, googling AX2 showed some other listings including amazon ones but couldn't locate the manual.

Will contact the seller and see if they can supply a english manual, other wise might have bought a dud.

As Ian says I think its only disconnecting a load that can cause damage- not starting with one hopefully doesn't hurt it.
