Protective Functions: – Stall prevention – Undervoltage
– Surge input – Overcurrent
– Drive overheating – Overvoltage
– External faults – Short circuit for output terminals
– CPU malfunction – Communication error
– Motor overload – Ground fault (at start)
(electronic thermal) – Output wiring not connected
– Memory error (during auto tuning only)
Keypad Digital Display - 4 digit LED
Drive Operation Output frequency, output current, output voltage, motor speed, line speed
(m/min), machine speed (r/min) can be displayed
Drive Setting Function Code and Setting Data can be displayed
Data Initializing Resets all Function Codes to initial factory settings
