FAULT / ERROR CODES DESCRIPTION
Over-current error
Electronic thermal overload error (motor current > bC110)
Dynamic braking resistor over used error
DC-Bus over-voltage error
Memory error / CPU error
Undervoltage error
Built-in current detector error
External trip error (digital input configured for Ext)
This error occurs if an operation command has been input to the inverter when the power supply is
turned ON. Operation command detection is carried out for 1 second after the power supply is turned
ON. (When USP function is selected.)
Ground fault error
Incoming voltage error (input power supply is too high)
Instantaneous power failure error
Temperature detector error
Temperature error Cooling fan rotation speed reduction error
Temperature error
Input open-phase error
When [bb-65] input phase loss selection is set to 01, and when a missing phase is detected in input line,
the inverter turns OFF its output.
IGBT error (ground fault to motor or on output of VFD)
When the output phase loss selection [bb-66] is set to 01, when a loose connection or disconnection of
output line, disconnection inside the motor, etc. is detected, the inverter turns OFF its output.
Detection of phase loss state is executed in the section between 5Hz to 100Hz.
Thermistor error
Brake error
Low-speed range overload error
Electronic thermal overload error (motor current > bC110)
Operator keypad communication error
RS485 / EZCOM communication error When CF-05 = 0 or 1
RTC error
Internal Program illegal instruction error
