Parker 591 governor maintenance

Model: Parker 590P governor

Fault cause: power on operation missing pulse alarm

Fault analysis: the customer Parker 591 governor is used for steel plate shearing and feeding. According to the customer‘s fault prompt, an alarm occurs during startup. The fault is that the six pulse armature current waveform loses a pulse. When the motor load exceeds 1.5 times the discontinuous point value, the alarm will be started. Most of the fault causes are harmonic interference, trigger board fault, loose plug and damaged thyristor. After measuring and eliminating peripheral faults, it is found that the output waveform is obviously asymmetric during operation. Measure the drive circuit and eliminate the problem of the main board. The thyristor is normal after measurement. It is found that the drive IC is damaged during power on online measurement. After replacement, the load test fault is removed.

Possible causes of Parker 591 governor alarm

Accts failed current transformer fault not connected to current transformer

Autotune abort auto tuning failure auto tuning extension is not flexible

Autotune error auto tuning operation error

Aux power fail auxiliary power failure

Checksum fail (EEPROM) checksum failed

The enable config configuration selects a valid state

Encoder failed encoder signal failure

Encoder alarm

Field fail excitation fault excitation current too low

Field over 1 excitation overcurrent motor excitation overcurrent

Health word normal word

Health store normal storage

Heatsink trip radiator overheat trip radiator fin overheat

Ia FBK cal fail armature current self test failed

Ia Inst cal fail armature current self test failed

Language checksum fail language mode selection error

Missing pulse missing armature current pulse

Over I trip motor armature overcurrent

Over speed

Over volts motor armature overvoltage

Phase lock PLL AC synchronization failed

Lack of preparation for pre peady fault

P3 state P3 port status warning

Speed FBK alarm

Stall trip locked rotor tripping Motor Locked Rotor timeout tripping

Thermistor motor overheating

Trip reset

3-phase failed 3-phase fault no 3-phase power supply
