28 iga Protective Functions Keypad display Protective functions Overcurrent Ground fault current Inverter Overload Overload trip Heat sink overheat Output Phase loss Over voltage Low voltage Electronic Thermal Input phase loss Descriptions The inverter turns off its output when the output current of the inverter flows more than 2% of the inverter rated current. The inverter turns off its output when a ground fault occurs and the ground fault current is more than the internal setting value of the inverter. The inverter turns off its output when the output current of the inverter flows more than the rated level (1% for 1 minute). The inverter turns off its output if the output current of the inverter flows at 1% of the inverter rated current for more than the current limit time (1min). The inverter turns off its output if the heat sink overheats due to a damaged cooling fan or an alien substance in the cooling fan by detecting the temperature of the heat sink. The inverter turns off its output when the one or more of the output (U, V, W) phase is open. The inverter detects the output current to check the phase loss of the output. The inverter turns off its output if the DC voltage of the main circuit increases higher than 4V when the motor decelerates. This fault can also occur due to a surge voltage generated at the power supply system. The inverter turns off its output if the DC voltage is below 18V because insufficient torque or overheating of the motor can occur when the input voltage of the inverter drops. 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. Inverter output is blocked when one of R, S, T is open or the electrolytic capacitor needs to be replaced. Self-diagnostic malfunction Parameter save error Displayed when IGBT damage, output phase short, output phase ground fault or output phase open occurs. 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 Remote keypad communication error Keypad error Cooling fan fault Instant cut off External fault A contact input External fault B contact input Operating method when the frequency command is lost Displayed when the inverter cannot communicate with the keypad. Displayed when the inverter and the remote keypad do not communicate with each other. It does not stop inverter operation. Displayed after the inverter resets the keypad when a keypad error occurs and this... Displayed when a fault condition occurs in the inverter cooling fan. Used for the emergency stop of the inverter. The inverter instantly turns off the output when the EST terminal is turned on. Caution: The inverter starts to regular operation when turning off the EST terminal while FX or RX terminal is ON. When multi-function input terminal (I2-I24) is set to 19 {External fault signal input A: (rmal Open Contact)}, the inverter turns off the output. When multi-function input terminal (I2-I24) is set to 19 {External fault signal input B: (rmal Close Contact)}, the inverter turns off the output. When inverter operation is set via analog input (-1V or -2mA input) or option (RS-48) and no signal is applied, operation is done according to the method set in I62 (Operating method when the frequency reference is lost). 28

29 Compact & Powerful Inverter iga Fault Remedy Keypad display Cause Remedy Caution: When an overcurrent fault occurs, operation must be started after the cause is removed to avoid damage to IGBT inside the inverter. Overcurrent Ground fault current Accel/Decel time is too short compared to the GD 2 of the load. Load is greater than the inverter rating. Inverter output is issued when the motor is free running. Output short circuit or ground fault has occurred. Mechanical brake of the motor is operating too fast. Ground fault has occurred at the output wiring of the inverter. The insulation of the motor is damaged due to heat. Increase the Accel/Decel time. Replace the inverter with appropriate capacity. Resume operation after stopping the motor or use H22 (Speed search). Check output wiring. Check the mechanical brake. Check the wiring of the output terminal. Replace the motor. Inverter overload Overload trip Load is greater than the inverter rating. Torque boost scale is set too large. Upgrade the capacity of motor and inverter or reduce the load weight. Reduce torque boost scale. Heat sink overheat Output Phase loss Cooling fan fault Over voltage Low voltage Electronic thermal External fault A contact input External fault B contact input Operating method when the frequency command is lost Remote keypad communication error Cooling system has faults. An old cooling fan is not replaced with a new one. Ambient temperature is too high. Faulty contact of magnetic switch at output. Faulty output wiring. An alien substance is clogged in a ventilating slot. Inverter has been in use without changing a cooling fan. Decel time is too short compared to the GD 2 of the load. Regenerative load is at the inverter output. Line voltage is too high. Line voltage is low. Load larger than line capacity is connected to line (ex: welding machine, motor with high starting current connected to the commercial line). Faulty magnetic switch at the input side of the inverter. Motor has overheated. Load is greater than inverter rating. ETH level is set too low. Inverter capacity is incorrectly selected. Inverter has been operated at low speed for too long. The terminal set to 18 (External fault- A) or 19 (External fault-b) in I2-I24 in I/O group is ON. frequency command is applied to V1 and I. Communication error between inverter keypad and remote keypad. - EEP: Parameter save error - HWT: Hardware fault - Err: Communication Error - COM: Keypad error Check for alien substances clogged in the heat sink. Replace the old cooling fan with a new one. Keep ambient temperature under C. Make connection of magnetic switch at output of the inverter securely. Check output wiring. Check the ventilating slot and remove the clogged substances. Replace the cooling fan. Increase the Decel time. Use Dynamic Brake Unit. Check whether line voltage exceeds its rating. Check whether line voltage is below its rating. Check the incoming AC line. Adjust the line capacity corresponding to the load. Change a magnetic switch. Reduce load weight and operating duty. Change inverter with higher capacity. Adjust ETH level to an appropriate level. Select correct inverter capacity. Install a cooling fan with a separate power supply. Eliminate the cause of fault at circuit connected to external fault terminal or cause of external fault input. Check the wiring of V1 and I and frequency reference level. Check for connection of communication line and connector. Contact your LSIS sales distributor. 29
