(if b120(brake control switch) was preset “01”) Is the brake working ON/OFF Preset B124 too short Brake signal/connection OK Option board 1 error 0–9 Detection of connected option card 1. For more details, refer to the instruction manual of the card. Make sure the connection of the card 1 Make sure if the usage is proper Option boad 2 error 0-9 Detection of connected option card 2. For more details, refer to the instruction manual of the card. Make sure the connection of the card 2 Make sure if the usage is proper Power off/ waiting from AC incoming voltage recovery Stand by condition because of low DC bus voltage such as power off, INV will shut the output. The detection level is same as under voltage trip. Any incoming AC V drop No contact failure in MCB,Mg? Check the DC bus voltage Perform above adjustment referring to d102, so that the DC bus voltage does not exceed the trip level. - - Instant power failure detection If Instant power failure 15ms or more happened, INV will shut the output. If the instant power failure is longer than preset allowable time or affordable control supply voltage time, INV will work as normal power off. This means INV will re-start with the run command after the long instant power failure. Any incoming AC V drop No contact failure in MCB,Mg? Over heat detection If main circuit temp. was exceeded specific level such as high ambient temp., fan failure, INV will shut the output. The temp. is detected at heat sink over 100 Celsius. Any cooling fan failure, disturbance of the cooling such as dusty fin. Installation vertical Ambient temp. high Gate array(INV domestic problem) If there was any communication error between micro processor and gate array, or if gate array can’t detect IGBT’s turn on/off such as IGBT failure. Any big noise near the INV Any IGBT failure Connection of flat cable/ribbon cable Input phase failure detection If one of incoming 3 phase voltage was missed, INV will shut the output if the detect function was preset. The detection delay is about 1 sec. Any missing phase No contact failure in MCB,Mg? IGBT over current detection (equivalent as power module) If instant over current happened between INV and the connected motor, INV will shut the output. Under this INV trip, the detected phase is possible to refer at d105 display. Even retry function is preset, INV can not retry after this detection. Short circuit or earth contact (ground fault) in the motor or the motor cable Any IGBT failure Any loose connection on main circuit such as power board Thermister(customer’s selection) If motor over temp. happened by integrated thermistor’s resistor value in the motor, INV will shut the output. Check the motor temp. Any thermistor failure in the motor Any noise in the thermistor signal Brake error (customer’s selection) After INV output brake release signal, INV couldn’t detect brake on/off within b124(waiting time for brake operation.
