There was an error occurred on the motor drive DC power supply PSA-200.
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 unit.
