Alarm in DC Power Supply for Motor Drive (PSA-200)

There was an error occurred to the DC power supply for motor drive (PSA-200) connected to a 200V AC servomotor equipped model.
No.
Alarm name
Cause
Countermeasure
1
Motor power supply voltage drop
The output voltage has dropped below the threshold.
  1. Check on the motor drive DC power supply (PSA-200).
    (Check such things as power voltage)
  2. There is a concern of malfunction on the motor drive DC power supply (PSA-200).
2
Fan error detection
The fan revolution has dropped or stopped.
  1. Check the connectivity of the fan unit.
  2. Replace the fan unit.
3
Excess regenerative electric discharge
Regenerative electric discharge in the internal regenerative resistance has risen above the threshold.
  1. Add a regenerative resistor unit.
4
Motor power supply excess voltage
The output voltage has risen a above the threshold.
  1. Check on the motor drive DC power supply (PSA-200).
    (Check such things as power voltage)
  2. Add a regenerative resistor unit.
5
PC board temperature error
The thermo sensor on the PC board had detected an overheat.
  1. Check the total wattage of the connected actuators.
  2. Check the ambient temperature.
  3. Add a regenerative resistor unit.
6
Power device overheated
The thermo sensor on the PC board had detected an overheat.
  1. Check the total wattage of the connected actuators.
  2. Check the ambient temperature.
  3. Add a regenerative resistor unit.
7
Critical malfunction
A non-recoverable error except for No. 1 to No. 6 was detected.
Replace the motor drive DC power supply.
