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 module.
0073 Pw sply: Over regeneration
Details
Over-regeneration detection level became over 100%. The regenerative resistor is overloaded. This
alarm cannot be reset for 15 min from the occurrence to protect the regeneration resistor. 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

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 emergency
stop signal is input.
Undefined number was selected for the rotary switch setting of the power supply.
