Page 72: Motor Drive Output
® ScopeMeter Test Tool MDA-550-III Test Tool Motor Drive Output The Motor Drive Output functions check the drive output conditions. The modulated output voltage varies with the motor speed and load. The output current depends on load and correct function of the motor. Unbalance between the phases can cause or indicate problems. The stress on the motor insulation can be determined by measurement of the risetime of a fast modulation pulse. -

Page 74: Spectrum
® ScopeMeter Test Tool MDA-550-III Test Tool Tips: • High voltage peaks can damage the motor insulation and drive output circuit and cause the drive to trip. Overshoot higher than 50 % of nominal voltage can be problematic. • Measure on the motor input to check the pulses on the input of the motor and the influence of the cable. -
Page 75: Voltage Unbalance
190 Series III Users Manual Voltage Unbalance The Voltage Unbalance checks for a difference between the Phase-Phase voltages for 3-phase systems. The unbalance value is calculated by dividing the maximum rms voltage deviation of one of the phases and the average rms voltage of all phases. Voltage unbalance at motor terminals can adversely affect motor operation and can also cause tripping of the current overload fault protection on the motor drive. -
Page 76: Motor Shaft
The Motor Shaft function detects bearing flash-over that can damage motor bearings. The measurement requires a connection to the rotating shaft of the motor. For this measurement, brushes are included as accessories. Alternatively, you can use a stranded wire probe. Fluke recommends the VP410 10:1 Voltage Probe. See Figure Figure 35. - Page 77 190 Series III Users Manual 6. Use one of the ground leads to contact the motor chassis that is the reference ground. When it is not possible to connect near the shaft, an extension cord with 4 mm connections on both ends is included for extending the connection to the ground lead. The measurement can be done on the driven and the non-driven end of the motor.
