Descriptions
Electronic
Thermal
The internal electronic thermal of the inverter determines the
overheating of the motor. If the motor is overloaded the inverter
turns off the output. The inverter cannot protect the motor
when driving a motor having more than 4 poles or multi
motors.
Input phase
loss Inverter output is blocked when one of R, S, T is open or the
electrolytic capacitor needs to be replaced.
Self-diagnostic
malfunction Displayed when IGBT damage, output phase short, output
phase ground fault or output phase open occurs.
Parameter
save error Displayed when user-setting parameters fails to be entered
into memory.
Inverter
hardware fault Displayed when an error occurs in the control circuitry of the
inverter.
Communication
Error Displayed when the inverter cannot communicate with the
keypad.
Remote
keypad
communication
error
Displayed when inverter and remote keypad does not
communicate each other. It does not stop Inverter operation.
Keypad error
Displayed after Inverter resets keypad when keypad error
occurs and this status is maintained for a certain time.
Cooling fan
fault Displayed when a fault condition occurs in the inverter cooling
fan.
Instant cut off
Used for the emergency stop of the inverter. The inverter
instantly turns off the output when the EST terminal is turned
on.
The inverter starts to regular operation when turning off the
EST terminal while FX or RX terminal is ON.
External fault A
contact input
When multi-function input terminal (I17-I20) is set to 18
{External fault signal input: A (Normal Open Contact)}, the
inverter turns off the output.
External fault B
contact input
When multi-function input terminal (I17-I20) is set to 19
{External fault signal input: B (Normal Close Contact)}, the
inverter turns off the output.
