Item 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 Excessive current has flown through the drive. 2 Overspeed The rotation speed of the motor output shaft exceeds approx. 120 % of maximum speed. 5 Overtemperature When the internal temperature of the drive exceeds the allowable temperature. 6 Overvoltage When the back electromotive force of the motor increases and the motor driving voltage inside the drive exceeds the allowable rated voltage. 8 Hall sensor Error There is a problem with the connection between the drive and the motor sensor. 9 Undervoltage When the input power voltage is lower than allowable minimum voltage. 10 Initial Operation Inhibition Power is applied while the FWD or REV input is on. The error will be activated only if the ‘No Operation at Initial Run’ parameter is set to 1. 11 System error There is a problem in the internal circuit board. 12 ROM error The stored data is damaged or the read/write of the EEPROM is failed. 13 Motor parameter error When motor parameters are not set or are outside the normal range. 15 External stop error When EXT-ERROR input is executed in direct IO (operates when EXT-ERROR input is set in direct IO). 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.
