Advice on spindle inverter spec

**JAZZCNC** · 14-09-2013

Does the Keb inverter let you set profiles for different motors.? Often decent VFD's do.! . . . . If so Why not use the same inverter for both and just switch between the two. (When switched off)

Rather annoyingly, the unit has been customised by ISEL and therefore the menu structure is not is non-standard and differs from the manual. KEB have no record of how it has been customised and ISEL germany are pretty useless in responding to any email that does not end up with them making some money.

I am considering buying another (£441) from KEB - but I am tight and would like a cheaper alternative!\

EDIT: I don't think it has profiles either so switching between machines could be a mission.

Nah don't do that you'll get a small inverter that will do what you want for £100-150 easy.

Let me have a look thru what I have, feel sure I have some that will do this OK.

The inverter should be capable of running any 3-phase motor. I don't really understand what ISEL could have done to the inverter other than use standard parameter settings? Are you sure you have the correct user manual? You should be able to "reset to factory defaults" and start again.

I once bought a panel with KEB drives. The local agent said he could download the parameters if I took the drive to him. Unfortunately they had a 3 phase input so I could not use them at home. Any drive of the rated capacity should work. Just check if the motor has a star/delta connection for 220v 3phase input depending on your supply. The v series from Yaskawa are very good and they used to have a plant in Scotland.

Good thinking. I might get back in touch with the KEB rep and see if he can reverse engineer the menus settings. I know you can connect it to a pc so I might try that too.
