590 governor repair case
Customer: a container manufacturing company in Huizhou
Steel plate shearing equipment
Model: Continental 590P speed
Fault causes: on the electricity to run PULSE MISSING alarm
Fault analysis: 590 customers in steel plate shear feeding governor is used, according to the customer‘s fault prompt is alarm occurs at startup, fault of six pulse armature current loss of a pulse waveform, the motor load is more than 1.5 times the DISCONTINUOUS (discontinuous point) value, start the alarm. Fault causes are: harmonic interference, trigger board fault, plug loose, controlled silicon damage. After the measurement of the external fault to the governor of the drive to measure the output waveform at run time has obvious asymmetry. Measurement of the drive circuit to exclude the motherboard problem for the control of silicon measurement, the power on line measurement found that the drive IC is damaged. Replacement with load test after lifting.
