5 Protective Functions Name Over-current protection Description Motor is restricted and decelerates rapidly, excessive current is drawn through the inverter and there is a risk of damage. Current protection circuit operates and the inverter output is switched off. At constant Speed On decelertion Speed On acceleration Speed Other Display of digital operator Display of remote operator/ Copy unit ERR *** OC. Drive OC. Decel OC. Accel Over. C Protective Functions Overload protection (Note ) Braking resistor overload protection Over-voltage protection EEPROM error (Note 2) Under-voltage CT error CPU error External trip USP error Ground fault protection Incoming over-voltage protection When the Inverter detects an overload in the motor, the internal electronic thermal overload operates and the inverter output is switched off. When DBTR exceeds the usage ratio of the regenerative Braking resister, the over-voltage circuit operates and the inverter output is switched off. When regenerative energy from the motor exceeds the maximum level, the over-voltage circuit operates and the inverter output is switched off. When EEPROM in the inverter is subject to radiated noise or unusual temperature rises, the inverter output is switched off. When the incoming voltage of inverter is low, the control circuit can't operate correctly. The under-voltage circuit operates and the inverter output is switched off When an abnormality occurs to a CT (current detector) in the inverter, the inverter output is switched off. When a mistaken action causes an error to the inbuilt CPU, the inverter output is switched off. When a signal is given to the EXT multifunctional input terminal, the inverter output is switched off. (on external trip function select) This is the error displayed when the inverter power is restored while still in the RUN mode. (Valid when the USP function is selected) When power is turned ON, this detects ground faults between the inverter output and the motor. When the incoming voltage is higher than the specification value, this detects it for 60 seconds then the over-voltage circuit operates and the inverter output is switched off. Over. L OL. BRD Over. V EEPROM Under. V CT CPU EXTERNAL USP GND. Flt. OV. SRC Temporary power loss protection When an instantaneous power failure occurs for more than 5ms, the inverter output is switched off. Once the instantaneous power failure wait time has elapsed and the power has not been restored it is regarded as a normal power failure. However, when the operation command is still ON with restart selection the inverter will restart. So please be careful of this. Inst.

FIN Gate Allay error Communication error between CPU and gate allay indicate GA Open-phase protection Overload protection 2 IGBT error Thermistor error Abnormal brake Option error 0-9 Option 2 error 0-9 During under-voltage waiting When an open-phase on the input supply occurs the inverter output is switched off. When the Inverter detects an overload in the motor (under 0.2Hz), the inverter output is switched off. When an instantaneous over-current is detected on the output the inverter output is switched off to protect the main devices. When the Inverter detects a high resistance on the thermistor input from the motor the inverter output is switched off. When inverter cannot detect switching of the brake (ON/FF) after releasing the brake, and for waiting for signal condition (b24) (When the braking control selection (b20) is enable.) These indicate the error of option. You can realize the details each instruction manual. These indicate the error of option 2. You can realize the details by each instruction manual. When the incoming voltage of the inverter has dropped, the inverter output is switched off and the inverter waits. Note : After a trip occurs and 0 seconds pass, restart with reset operation. 2: When EEPROM error occors, confirm the setting date again. PH. Fail Over. L2 IGBT TH BRAKE OP-09 OP2-09 UV. WAIT 4
