Protective structure IP20
Control system Sine-wave PWM control
Output frequency range 0.1 to 400 Hz
Frequency accuracy
Within ±0.01% of the maximum output frequency for digital input, within ±0.2% of maximum frequency
for digital input (at 25±10
°C)
Frequency setting
resolution
Digital input: 0.01 Hz
Analog input: Maximum output frequency/4000
(O terminal input: 12 bits/0 to +10 V, O2 terminal input: 12 bits/-10 to +10 V, OI terminal input: 12 bits/0
to +20 mA)
Voltage/frequency
characteristic V/f characteristic variable with the base frequency set between 30 to 400 Hz, constant- or
reduced-torque V/f control, sensorless vector control, 0Hz-range sensorless vector control
Speed fluctuation ±0.5% (with sensorless vector control or 0Hz-range sensorless vector control)
Rated overload current 150%/60 seconds, 200%/3 seconds
Acceleration/deceleration
time
0.01 to 3,600.0 seconds (in linear or curved pattern)
200%/0.3 Hz (with sensorless vector control or 0Hz-range sensorless vector control)
Starting torque 150%/0Hz-range torque (with 0Hz-range sensorless vector control or with a motor of capacity one
class lower than the inverter connected)
DC braking
Triggered at motor start-up, when the actual motor frequency exceeds the acceleration frequency set
by a stop command, when the actual motor frequency exceeds the frequency set by a frequency
command, or by an externally input command (braking force, time, and frequency are variable).
