Main control properties
Range of speed regulation
High torque output, starting torque can reach 150% at 1Hz.
Digital setting: ¡À0.01%; analog setting: ¡À0.2%
Digital setting: 0.01Hz; analog setting: 0.1% of the max. frequency
3 modes: start from start frequency, start after brake and start after rotating speed tracking
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
3 modes: decelerated stop, decelerated stop+DC braking and free stop
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
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.
