Lenze 8200 VFD Inverter - Spindle motor not moving

[Fgc]

Thanks for replies.

Magicniner- The inverter is original equipment that was built in by Emco and the spindle was working properly before the prolonged storage. so i did not do any commissioning when i powered up the cnc lathe.

Eddycurrent - do you know if the lenze relies on batteries to remember motor parameters? how does the capacitor reforming help and how do i go about doing it?

If you think it may have lost parameters it's worth trying, reforming the caps is a very good suggestion if the VFD has been stored for a significant period without power,

I don't know about the battery but there is information here, for example, about capacitors; https://www.youtube.com/watch?v=HuALonM_1X4

Roughly speaking a VFD goes from AC input, through a recifier to what is called the DC bus and the capacitors there act as a reservoir before the DC is chopped up into a synthesised sine wave of variable frequency.

I've just seen on page 28 of the manual; http://download.lenze.com/TD/E82EV__...__v3-0__EN.pdf
it says; Storage > 2 years: form the DC bus capacitors.

Page 202 of the manual goes on to say;

Stop!
Special commissioning procedure after long−term storage
If controllers are stored for more than two years, the insulation resistance of
the electrolyte may have changed.
Possible consequences:
ƒ During initial switch−on, the DC−bus capacitors and hence the controller are
damaged.
Protective measures:
ƒ Form the DC−bus capacitors prior to commissioning. Instructions can be
found on the Internet (www.Lenze.com).

Or maybe nobody cares any more ?

thanks for the info. appreciate you taking time to send them. i had to travel so didn't have time to log in to check forum.
looking at the info, it seems quite daunting a task to to recommission a machine from long storage :-(
