Sinusoidal PWM control
0.5 to 320 Hz (0.5 to 80Hz default setting)*. Maximum frequency
is adjustable between 30 and 320 Hz.
0.1Hz input from the operating panel, 0.2 Hz analog
input (@ maximum frequency of 100 Hz).
Analog setting: ±0.5% of the maximum output frequency or less
@ 25°C±10°C,
Digital setting: ±0.01% of the maximum output frequency or less
@ -10°C to +50°C
Constant V/f, variable torque mode, sensorless vector control
mode, automatic torque boost mode, base frequency adjustment
(25 to 320Hz), and torque boost adjustment (0 to 30%).

Built-in potentiometer on the front panel, external potentiometer
(1k ohm to 10k ohm variable resistor connectable), 0 to 10Vdc
(input impedance: VIA = 30.55k ohm, VIB=30k ohm),
4 to 20mAdc (input impedance = 400 ohm), and optional
characteristics (gain,bias) can be preset by 2-point setting
Proportional gain, integral gain adjustments.
Adjustable between 0 and 10Hz

Adjustable between 2.2 and 12kHz (default = 12kHz)
0.1 to 3600 secs, accel/decel time 1 or 2 selectable, S1 and S2
accel/decel pattern selectable
Jog run from panel with JOG mode selection. Terminal block
operation possible with parameter settings (see page 37).
Set frequency +15 preset speeds possible with open/closed
combinations of SS1, SS2, SS3, SS4 and CC
A maximum of ten automatic retries are selectable (see page 38)
Retry will occur immediately after a self evaluation of the main
circuit is completed.
Externally connected braking resistor (optional)
Braking start frequency (0 to max frequency), braking level
(0 to 100%), braking time (0 to 20 seconds).
