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
Adjustable max.braking torque.
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.
Fast current limit
Fast current restraining ability prevents frequent over-current trips and realize the characteristics of excavator (output torque is kept for locked-rotor of motors).
Automatic carrier regulation
Carrier frequency can be automatically regulated to optimize system state in accordance with load characteristics.
