KTK DC Drive Fault.
KTK DC Drive Fault.
(OP)
Hi,
I have a problem with a KTK 6P4Q7.5 Drive.
The drive is 3phase 415V 50Hz input. (UK).
Fitted to a Bridgeport Interact 4 miller.
Drives the Spindle motor.
Initially the machine / drive lost a phase (faulty 3ph switch).
Replaced switch.
3phase ok to drive card, and all other start/enable signals appear ok.
Motor does not turn.
Press Red reset on drive card, motor turns (backwards) for about 1second, then stops.
Centre of drive card there is an led marked " instrip ", which lights up.
There is also a two digit display on the card which is reading " 00 ".
Any idea's what could be wrong ??.
Regards,
mrbj.
