Hello everyone,
Some advice would be helpfull with a problem regarding a DC drive controled by a SLC 5/05.
200 HP drive with stop, start, jog, fast and slow controled via slc.
PROBLEM: No speed control when drive is started. Anolog card maintains a 4V speed reference to drive, even when stopped. Prior speed reference would be 0V when stopped.
I would guess anolog card, but other 120V outputs are missing controling other functions not related to drive.
OBSERVATION: Plant had a utility problem distroying the voltage regulator/line conditioner supplying the SLC. The SLC was supplyed without a voltage reg./line cond. for appox. 24hrs until one was installed. Since this SLC is installed in the drive cabinet, it was expectable to SCR notching for 24hrs. Speed and output problems showed up shortly after.
Any advice would be very helpfull.
