25. troubleshooting Be alert High voltages can cause serious or fatal injury Before troubleshooting Perform the following steps before starting any procedure in this section 1 Disconnect AC line voltage from the drive 2 Check the drive closely for damaged components 3 Check that no conductive or other foreign material is lodged on the printed circuit board 4 Verify that every connection is correct and in good condition 5 Verify that there are no short circuits or grounded connections 6 Check that the voltage selection switch settings match the AC line and output voltages Problem Possible Causes 37 Suggested Solutions Line fuse blows Motor runs too fast at maximum speed setting Line fuses are the wrong size Motor cable or armature is shorted to ground Nuisance tripping caused by a combination of ambient conditions and high current spikes i e reversing MIN SPD and MAX SPD settings are too high Check that line fuses are the correct size Check motor cable and armature for shorts Add a blower to cool the drive components increase CURR LIMIT or TORQ LIMIT settings Recalibrate MIN SPD and MAX SPD 38 Problem Possible Causes Suggested Solutions Line fuse is not blown but the motor does not run Speed adjust potentiometer or voltage input signal is set to zero speed Speed adjust pot
