External Trip
Use this function to trip the Inverter according to the peripheral system conditions.
•When the EXT terminal is turned on, E12 is displayed and the Inverter trips to stop output.
•Allocate 12 (EXT) to the desired multi-function input.
(Example 1) 0 Hz start
• Starts at 0 Hz regardless of motor rotation
speed. The retry wait time is ignored.
• An overcurrent trip may occur with this start at
a high motor speed.
(Example 2) Frequency pull-in restart
• After the FRS terminal is turned off, the motor
frequency is matched and a frequency pull-in
restart is performed without stopping the motor.
If an overcurrent trip occurs, extend the retry
wait time.
