Protective and Diagnostic Functions ● Error Code List Selection Features SYSDRIVE Option Overview of Inverter Selection SYSDRIVE JX Series SYSDRIVE MX Series SYSDRIVE RX Series *1. After a trip occurs, normal operation is restored in 10 seconds by resetting. *2. Check the set data again if the EEPROM error occurs. *3. If the power is shut off during data initialization, an EEPROM error may occur when the power is next turned on. Shut off the power after completing data initialization or copying. *4. If an undervoltage trip occurs with the USP terminal set to ON, the trip, after released by resetting, becomes a USP error . Reset again to release the trip. *5.
The ground fault trip cannot be released with the reset input. Shut off the power and check the wiring. *6. If the multi-function output (relay output) is set to 05 (alarm), the signal may not be output during the CPU error . In this case, no data is stored in the trip monitor. ek k0k8 ek k0k8 ek k1k4 ek k0k9 ek k1k3 ek k2k2 Multi-functional Compact Inverters SYSDRIVE MX Series 35 Display on Digital Operator Name Description ek k0k1 Overcurrent trip Constant speed If the motor is restrained or rapidly accelerated or decelerated, a large current will flow through the Inverter, which will result in breakage.
To avoid this, an overcurrent protection circuit works to shut off the Inverter output. ek k0k2 Deceleration ek k0k3 Acceleration ek k0k4 Others ek k0k5 Overload trip *1 If an Inverter output current is detected and the motor is overloaded, an electronic thermal inside the Inverter works to shut off the Inverter output. ek k0k6 Braking resistor overload trip When the usage rate of the braking resistor is exceeded, this function detects overvoltage due to operation stop of the control circuit and shuts off the Inverter output.
ek k0k7 Overvoltage trip If the incoming voltage and regenerative energy from the motor are too high, a protection circuit works to shut off the Inverter output when the voltage on the converter exceeds the specified level. ek k0k8 EEPROM error *2 *3 Shuts off the output if an error occurs in the EEPROM built into the Inverter due to external noise and abnormal temperature rise. ek k0k9 Undervoltage trip Shuts off the output if the incoming voltage drops below the specified level, causing the control circuit not to work properly during a momentary power interruption. ek k1k1 CPU error *6 Shuts off the output if the internal CPU has worked erroneously or abnormally.
ek k2k2 ek k1k2 External trip If an error occurs in the external equipment or devices, the Inverter receives the signal, and the output is shut off. (Available with the external trip function selected) ek k1k3 USP trip *4 Appears if the Inverter is turned on with the RUN command being input. (Available with the USP function selected) ek k1k4 Ground fault trip *5 Shuts off the output if a ground fault between the Inverter output unit and the motor is detected when turning on the power. ek k1k5 Incoming overvoltage trip Appears if the incoming voltage has remained high for 100 seconds while the Inverter output is stopped.
ek k2k1 Temperature error Shuts off the output if the temperature has risen in the main circuit due to malfunction of the cooling fan or other reason. ek k2k3 Gate array error Displayed when a fault is detected in communication behavior between the built-in CPU and the gate array. ek k3k5 Thermistor error (Available when the thermistor trip function is used) Detects the resistance of the external thermistor and shuts off the Inverter output.
