Output Frequency/Stop Display: 4-digit, 7-segment LED displays output frequency, stall prevention, overvoltage limit, overload, power-source undervoltage, DC circuit undervoltage, and executing retry. Parameters include setting error, upper limit, and lower limit.
Fault Causes: Overcurrent, overvoltage, heatsink overheat, load-side short circuit, load-side ground fault, inverter overload, armature overcurrent during start-up, load-side overcurrent during start-up, dynamic braking unit overcurrent/overload, emergency stop, EEPROM error, RAM error, ROM error, communication error, undervoltage, low current, overtorque, open output phase, and motor overload.
Monitor Functions: Terminal input/output status, forward/reverse, frequency setting value, output current, DC current, output voltage, output power, torque current, cumulative run time, past faults, and overload ratio.
Selectable Units Display: Can select frequency display to match motor speed, line speed, etc. Selection of display of current in amperes/%, voltage in volts/%.
Edit Function: Automatic editing of parameters differing from standard values. Allows for easy searching of changed parameters.
Blind Function: Select to not display unneeded parameter groups.
User Settings Initialization: Saving of user parameter values for initialization resetting possible. Parameters can be easily reset to user default setting values.
