Inverter Specifications
Chapter 9-1
Note
1.
The power supply capacity is the capacity for the Inverter’s rated output. It
will vary depending on the impedance at the input power supply. (This is
due to fluctuations in the power factor. The power factor can be improved
by inserting an AC reactor.) There will also be variations in the ratio
between the rated current of the motor that is used and the rated output
current of the Inverter.
2.
The heat radiation is the electric power consumed in the Inverter at the
Inverter’s rated output.
Control

function
Motor protection
Protection by electronic thermal
Instantaneous overcurrent
protection
Stops at approx. 250% of rated output current
Overload protection
Stops in 1 min at approximately 150% of rated output current
Overvoltage protection
Stops when main-circuit DC voltage is approximately 410 V
Undervoltage protection
Stops when main-circuit DC voltage is approximately 200 V

Momentary power
Stops for 15 ms or more. By setting the Inverter to momentary
interruption compensation
(selection)
power interruption mode, operation can be continued if power is
restored within approximately 0.5 s.
