Indication Color Function Description Power LED Green Power Status Lights up when power is applied. Error LED Red Error Status Flashes when an error occurs. Communication LED Yellow RS-485 Comm. Status Flashes when the drive and the master communicate with RS-485. - ● List of Error Types by the Number of LED Blinking
-
No. Error Type Causes 1 Overcurrent The current through power devices in drive exceeds the limit. 2 Overspeed The motor speed exceeds 4,400 r/min. 5 Overtemperature Internal temperature of the drive exceeds 85℃. 6 Overvoltage · Power voltage exceeds the rated voltage by more than 20%.
· Load with large inertia is suddenly started or stopped.8 Sensor Error There is a problem with the connection between the drive and the motor sensor. 9 Undervoltage Power voltage is 40% lower than the rated voltage. 11 Internal Circuit Error There is a problem in the internal circuit board. 12 EEPROM Error The stored data is damaged or the read/write of the EEPROM is failed. 16 External Error EXT-Error input signal is received. 17 Initial Operation Inhibition Power is applied while FWD or REV input is on, and ‘No Operation at Initial Run’ parameter is set to 1. 18 RS-485 Comm. Error The number of RS-485 comm. errors reaches the value set inn the ‘comm error alarm’ parameter. 19 RS-485 Comm. Time Out Communication is not established for the time set in ‘comm time out’ parameter.
