Power supply alarms
0061 Pw sply: Pwr module overcurnt
Details
Overcurrent protection function in the power module has started its operation.
0062 Pw sply: Frequency error
Details
The input power supply frequency increased above the specification range.
0066 Pw sply: Process error
Details
An error occurred in the process cycle.
0067 Pw sply: Phase interruption
Details
An open-phase condition was detected in input power supply circuit.
0068 Pw sply: Watchdog
Details
The system does not operate correctly.
0069 Pw sply: Grounding
Details
The motor power cable is in contact with FG (Frame Ground).
006A Pw sply: Ext contactor weld
Details
A contact of the external contactor is welding.
006B Pw sply: Rush circuit error
Details
An error was detected in the rush circuit.
006C Pw sply: Main circuit error
Details
An error was detected in charging operation of the main circuit capacitor.
006D Pw sply: Parameter error
Details
An error was detected in the parameter sent from the drive unit.
006E Pw sply: H/W error
Details
An error was detected in the internal memory.
An error was detected in the A/D converter.
An error was detected in the unit identification.
006F Power supply error
Details
No power supply is connected to the drive unit, or a communication error was detected.
0070 Pw sply: External EMG stop err
Details
A mismatch of the external emergency stop input and NC emergency stop input continued for
30 seconds.
0071 Pw sply: Instant pwr interrupt
Details
The power was momentarily interrupted.
0072 Pw sply: Fan stop
Details
A cooling fan built in the power supply unit stopped, and overheat occurred in the power mod-
ule.
0073 Pw sply: Over regeneration
Details
Over-regeneration detection level became over 100%. The regenerative resistor is overload-
ed. This alarm cannot be reset for 15 min from the occurrence to protect the regeneration re-
sistor. Leave the drive system energized for more than 15 min, then turn the power ON to
reset the alarm.
0074 Pw sply: Option unit error
Details
An alarm was detected in the power backup unit (power supply option unit).
Check the LED display on the power backup unit to identify what alarm is occurring to the unit.
Refer to the instruction manual of your drive unit for details.
0075 Pw sply: Overvoltage
Details
L+ and L- bus voltage in main circuit exceeded the allowable value. As the voltage between
L+ and L- is high immediately after this alarm, another alarm may occur if this alarm is reset
in a short time. Wait more than 5 min before resetting so that the voltage drops.
0076 Pw sply: Function setting err
Details
The rotary switch setting of external emergency stop is not correct, or a wrong external emer-
gency stop signal is input.
Undefined number was selected for the rotary switch setting of the power supply.
