Protective structure IP20 IP00
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(carrier
frequency: 3kHz below),vector control(use option SJ-FB)
Rated overload current 120% / 60 seconds every 10min
Acceleration/deceleration
time
0.01 to 3,600.0 seconds (in linear or curved pattern)
Starting torque
150% / 0.5 Hz (with sensorless vector control)
120% / 0.5Hz (do to）
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).
