What to do if the line fuse blows in my Minarik MM20000A DC Drives?
If the line fuse blows, first check that the line fuses are the correct size (3 A). Also, check the motor cable and armature for shorts to ground. If nuisance tripping occurs due to ambient conditions and high-current spikes, decrease the TORQUE setting. If the field circuit is shorted, send the drive to the Minarik repair department.
What to do if the line fuse doesn't blow but the Minarik MM20000A motor doesn't run?
If the line fuse doesn't blow but the motor doesn't run, increase the speed adjust pot or reference voltage setting. Check that the speed adjust pot or reference voltage connections are not open. Verify that the motor is not jammed and increase the TORQUE setting. Apply AC line voltage to L1 and L2. Connect the motor to A1 and A2.
How to fix motor running too fast at maximum speed setting in Minarik MM20000A?
If the motor runs too fast at the maximum speed setting, recalibrate the MIN SPD and MAX SPD. Also, check the field connections if you are using shunt-wound motors.
What to do if Minarik MM20000A DC Drives motor pulsates or surges under load?
If the motor pulsates or surges under load, adjust the IR COMP setting slightly CCW until the motor speed stabilizes.
