(2) Power supply alarm
(Note 1) If a power supply alarm (60 to 77) occurs, all servos will stop with the dynamic brakes, and all spindles will coast to a stop.
(Note 2) "b", "C" and "d" displayed on the power supply unit's LED as a solid light (not flickering) do not indicate an alarm.
(Note 3) Check the LED display of the power backup unit to identify what alarm is occurring to the power backup unit.
**Refer to "9.5.2 List of Power Backup Function Alarms".
(Note 4) When the power supply alarm (6F) is detected in the 2nd part system, the reset method differs depending on the detected
power supply alarm.
No.
Name
Details
Reset
method
61 Power supply: Power module overcurrent
Overcurrent protection function in the power module has started its operation.
PR
62 Power supply: Frequency error
The input power supply frequency increased above the specification range.
PR
66 Power supply: Process error
An error occurred in the process cycle.
PR
67 Power supply: Phase interruption
An open-phase condition was detected in input power supply circuit.
PR
68 Power supply: Watchdog
The system does not operate correctly. LED display is fixed as "8".
AR
69 Power supply: Grounding
The motor power cable is in contact with FG (Frame Ground).
PR
6A Power supply: External contactor welding
A contact of the external contactor is welding.
PR
6B Power supply: Rush circuit error
An error was detected in the rush circuit.
PR
6C Power supply: Main circuit error
An error was detected in charging operation of the main circuit capacitor.
PR
6D Parameter setting error
An error was detected in the parameter sent from the drive unit.
PR
6E Power supply: H/W error
An error was detected in the internal memory.
AR
A/D error
An error was detected in the A/D converter.
Unit ID error
An error was detected in the unit identification.
6F Power supply error
No power supply is connected to the drive unit, or a communication error was
detected.
AR
(Note 4)
70 Power supply: External emergency stop er-
ror
A mismatch of the external emergency stop input and NC emergency stop input
continued for 30 seconds.
PR
71 Power supply: Instantaneous power inter-
ruption
The power was momentarily interrupted.
NR
72 Power supply: Fan stop
A cooling fan built in the power supply unit stopped, and overheat occurred in
the power module.
PR
73 Power supply: Over regeneration
Over-regeneration detection level became over 100%. The regenerative resistor
is overloaded. This alarm cannot be reset for 15 min from the occurrence to pro-
tect the regeneration resistor. Leave the drive system energized for more than
15 min, then turn the power ON to reset the alarm.
NR
74 Power supply: Option unit error
An alarm was detected in the power backup unit (power supply option unit).
NR
(Note 3)
75 Power supply: Overvoltage
L+ and L- bus voltage in main circuit exceeded the allowable value. As the volt-
age 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.
NR
76 Power supply: Function setting error
The rotary switch setting of external emergency stop is not correct, or a wrong
external emergency stop signal is input.
AR
Power supply: Function selection error
Undefined area for the rotary switch is selected
77 Power supply: Power module overheat
Thermal protection function in the power module has started its operation.
