- D090Error codeDisplays programming error code
- D102Error codeDisplays the DC Bus voltage
- D104Error codeDisplays the motor electronic thermal overload estimated temperature ratio. If the value reaches 100%, the inverter will trip (E05)
- E0Error codeIf the motor is constrained or suddenly accelerated or decelerated, a high current will flow in the inverter and the inverter may fail. To avoid this problem, the inverter shuts off its output and displays the error code shown on the left when it detects a current higher than a specified level. This protective function uses a DC current detector (CT) to detect over-current. When a current as high as about 220% of the inverter's rated output current is detected, the protective circuit operates and the inverter trips
- E1Error codeCPU error
- E02Error code
- E2Error codeIf the main circuit temperature rises because of a high ambient temperature or for other reasons, the inverter will shut OFF its output
- E03Error code
- E04Error code
- E05Error codeThis protective function monitors the inverter output current, and shuts off the inverter output and displays the error code shown on the left when the internal electronic thermal protection circuit detects a motor overload. If the error occurs, the inverter will trip according to the setting of the electronic thermal function
- E06Error codeWhen the BRD operation rate exceeds the setting of B090, this protective function shuts off the inverter output and displays the error code shown on the left
- E07Error codeIf the DC voltage across the P and N terminals rises too high, an inverter failure may result. To avoid this problem, this protective function shuts off the inverter output and displays the error code shown on the left when the DC voltage across the P and N terminals exceeds a specified level because of an increase in the energy regenerated by the motor or the input voltage (during operation). The inverter will trip if the DC voltage across the P and N terminals exceeds about 400 VDC (in case of the 200 V class models) or about 800 VDC (in case of the 400 V class models)
- E08Error codeWhen an internal-EEPROM is caused by external noise or an abnormal temperature rise, the inverter shuts off its output and displays the error code shown on the left. Note: An EEPROM error may result in a CPU error
- E09Error codeIf the inverter input voltage drops, the control circuit of the inverter cannot function normally. Therefore, the inverter shuts off its output when the input voltage falls below a specified level. The inverter will trip if the DC voltage across the P and N terminals exceeds about 175 VDC (in case of the 200 V class models) or about 345 VDC (in case of the 400 V class models)
- E10Error codeCT (current transformer) error
- E12Error codeIf an error occurs in the external equip- ment or device connected to the inverter, the inverter will latch the error signal and shut off its output. (This protective function is active when the external trip function is enabled.)
- E13Error codeA USP error is indicated when the inverter power is turned on with an input operation signal remaining in the inverter. (This protective function is active when the USP function is enabled.)
- E14Error codeGround fault
- E15Error codeThis protective function determines an error if the input voltage is kept above the specification level for 100 seconds while the inverter is stopped. The inverter will trip if the DC voltage of the main circuit is kept above about 390 VDC (in case of the 200 V class models) or about 780 VDC (in case of the 400 V class models)
- E16Error codeIf an instantaneous power failure lasts 15 ms or more, the inverter will shut off its output. When the power failure duration is long, the inverter assumes a normal power-OFF. If a restart mode has been selected and an operation command remains in the inverter, the inverter will restart after the power is recovered
- E20Error codeInverter thermal trip with low fan speed
- E23Error codeGate array error
- E25Error codeMain circuit error
- E30Error codeIf instantaneous over-current occurs, the main circuit element temperature is abnormal, or the main circuit element drive power drops, the inverter will turn OFF its output to protect the main circuit element. (After tripping because of this protective function, the inverter cannot retry the operation.)
- E35Error codeThe inverter monitors the resistance of the thermistor (in the motor) connected to the inverter’s [TH] terminal, and will turn OFF the inverter output if the motor temperature rises
- E37Error codeIf the EMR signal (on three terminals) is turned ON when the slide switch (SW1) on the logic board is set to ON, the inverter hardware will turn OFF the inverter output and display the error code shown on the left. The malfunction is due to incoming noise when EMR terminal is not ON
- E38Error codeIf overload occurs during the motor operation at a very low speed at 0.2 Hz or less, the electronic thermal protection circuit in the inverter will detect the overload and shut off the inverter output (2nd electronic thermal control). Note: A high frequency may be recorded as the error history data
- E41Error codeIf time-out occurs because of line discon- nection during the communication in ModBus-RTU mode, the inverter will display the error code shown on the left. (The inverter will trip according to the setting of C076.)
- E60Error codeThe inverter detects errors in the option board mounted in the optional slot 1. For details, refer to the instruction manual for the mounted option board
