We are using Control Techniques AC Drive 15 KW for our machine.
The drive functions well when we mount it on a table but does start up and no display come hwen we mount it on panel.
What can cause this strange behaviour
Thanks in advance.

Hello Chaterpilar
Can you give us more details, ie model, age, voltage etc then maybe someone can help.

Dear Marke,
Another input is the drive was OFF for 6 days before it was restarted, and the ambience is dusty ( fine powder which is conductive)

Hello chaterpilar
I think that your comment about the dusty environment with a conductive dust is a very good clue.
If there is a build up of conductive dust on parts of the circuit, it will certainly cause problems. In the wrong places, it could cause a major failure with highvoltage getting into low voltage circuits.
I would suggest that you give it a very good clean up, and then protect it well from conductive dust contamination.
