Troubleshooting 9-9
IGDPS Boards MV SMC units provided with optional stop capabilities (soft stop, linear
deceleration or pump control) utilize isolated gate drive power supply
(IGDPS) boards. These boards provide a continuous source of power to
the gate drive boards. The IGDPS boards are fed from a 50 V DC power
supply provided with the MV SMC.
The circuitry for the IGDPS is encapsulated in epoxy. As a result the
board can not be field repaired and there are no internal test points or
adjustments available. If one of the six (6) isolated 20 V DC outputs fails,
the entire board must be replaced.
