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
charac-
teristics Overload capacity 150% of rated output current for 1 min
External frequency set signal Selectable with FREQ adjuster: 0 to 10 V DC (20 kW), 4 to 20 mA (250
W), and 0 to 20 mA (250 W)
Acceleration/deceleration time 0.0 to 999 s (Independent acceleration and deceleration time settings:
2 types)
Braking torque Approx. 20% (Braking Resistor and Braking Unit cannot be
connected.)
Voltage/frequency
characteristics Set a user V/f pattern
Protection
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
(160 V for single-phase 200-V AC model)
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.
Cooling fin overheating Detects at 110°C ±10°C
Grounding protection Protection at rated output current level
Charge indicator (RUN indicator) Lit when the main circuit DC voltage is approximately 50 V or less.
