Approx. 20% (125 to 150% possible with braking resistor)
Set voltage vector control/user V/f pattern
Protection by electronic thermal
Stops at approx. 250% of rated output current
Stops in 1 min at approximately 150% of rated output current
Stops when main-circuit DC voltage is approximately 410 V
Stops when main-circuit DC voltage is approximately 200 V
(160 V for single-phase 200-VAC model)
Stops for 15 ms or more. By setting the Inverter to momentary
power interruption mode, operation can be continued if power is
restored within approximately 0.5 s.
Detects at 110°C ± 10°C
Protection at overcurrent detection level
Lit when the main circuit DC voltage is approximately 50 V or
less.
