1:100

Torque characteristics

High torque output, starting torque can reach 150% at 1Hz.

Frequency accuracy

Digital setting: 0.01%; analog setting: 0.2%

Frequency resolution

Digital setting: 0.01Hz; analog setting: 0.1% of the max. frequency

Start modes

3 modes: start from start frequency, start after brake and start after rotating speed tracking

Acceleration/

deceleration modes

3 modes: straight line mode, settable S-curve mode (independently adjustable proportions of start and end sections of S-curve) and automatic acceleration and deceleration mode

Stop modes

3 modes: decelerated stop, decelerated stop+DC braking and free stop

DC braking

Start frequency of braking: 0~60.00Hz, or determined by external input terminals.

Braking time: 0.0~60.0s, or determined by external input terminals.

Braking current: 0.0~100.0% of the rated current of frequency converters

Jog

Range of jog frequency: 0.00~upper limiting frequency; jog acceleration/deceleration time: 0.0~6553.5s; jog interval can be set.

Automatic voltage regulation

When input power grid voltage fluctuates, stability of output voltage can be kept automatically.
