Product introduction
Features
● Built-in bypass contactor to simplify customer external wiring.
● Six starting modes are selected to maximize the best starting effect of the motor.
● The original swing starting mode has good starting effect for eccentric load.
● It can realize the forward and reverse step wise frequency conversion inching
function, and realize the forward and reverse inching operation of the motor.
● Three parking modes can be selected: free parking,soft parking and DC braking
parking.
● Two driving modes can be selected: torque mode and smooth mode.
● Two independent programmable output relays: it can easily realize interlocking
control with other equipment, and has delay action function with adjustable delay time.
● Three phase current value can be displayed at the same time, and the current value
can be calibrated independently.
Large screen LCD man-machine interface, Chinese (Chinese display) and
English display modes, easy to operate.
● Multiple protection and monitoring functions.The thermal overload protection
can be adjusted according to the load requirements. Multiple protection functions
can be opened and closed independently.
● The last 12 fault records can be queried to provide fault analysis basis.
● A group of 4 ~ 20mA (0 ~ 20mA) analog output.
● Modbus RTU communication (RS485) can enter parameter setting, operation
and monitoring through the upper computer to realize high intelligent control.
Actual power setting:when the power of the soft starter is greater than the actual
load power,the rated current of the soft starter can be set according to the actual load
to match the actual power of the soft starter with the load,so as to ensure the accuracy
of starting, operation, protection and other parameters.
