Note
•
If operated within the rated output, the ”S” Series inverter is designed to withstand instantaneous
power interruptions within 15 ms and maintain normal operation. Based on the rated heavy load
current, safe operation during an instantaneous power interruption is guaranteed for 200V and
400V inverters (whose rated input voltages are 200-240 VAC and 380-480 VAC respectively).
•
The DC voltage inside the inverter may vary depending on the output load. If the power
interruption time is longer than 15 ms, a low voltage trip may occur.
When operating in sensorless II mode while the load is spinning, the speed search function (for general
acceleration) must be set for smooth operation. If the speed search function is not set, an overcurrent
trip or overload trip may occur.
Auto Restart Settings
When inverter operation stops due to a fault, the inverter automatically restarts based on the
parameter settings.
