Electronic thermal overload error (motor current > bC110)
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
Incoming voltage error (input power supply is too high)
Temperature error Cooling fan rotation speed reduction error
When [bb-65] input phase loss selection is set to 01, and when a missing phase is detected in input line,
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.
Electronic thermal overload error (motor current > bC110)
RS485 / EZCOM communication error When CF-05 = 0 or 1
