YCQR2 Intelligent Motor Soft Starter
General
There are also a series of problems during the start-up or stopping of the squirrel
cage induction motor.Such as the impact of the impact of the full pressure when the
starting shock to the system, the impact of the starting current on the grid shocks,in
contract cooper loss is rising.When in shutdown, if loss torque drive system
suddenly, relying on friction torque to overcome system coasting stop, but also
bring huge problems to the drive system, such as pump the ditch hammer
phenomenon,Smooth deceleration parking, eliminating the inertia impact of the
drag system. A Complete system protection function can prolong the service life of
the system, reduce the maintenance cost, and increase the reliability of, compatible
with the all starting devices of various function, is traditional start star delta starter,
self coupling decompression starting, magnetron step-down starting the ideal
replacement product.
Traditional method of starting motor is Y-△starter and auto transformer starter. They
can only start reduce the impact of motor current to the power grid. It can guarantee
the reliable starting of the motor, but can't solve the above problems.ZJR series
motor soft starter with intelligent digital control, micro controller as central
intelligent, controllable silicon module for the implementation of components, fully
automatic motor control. It is used in various load of squirrel cage asynchronous
motor starting .The motor can be smoothly activated in any case, protect the
application system, reduce the impact of the starting current on the grid, and ensure
the reliable starting of the motor.A Complete system protection function can prolong
the service life of the system, reduce the maintenance cost, and increase the
reliability of, compatible with the all starting devices of various function, is traditional
start star delta starter, self coupling decompression starting, magnetron step-down
starting the ideal replacement product.
The soft starter has the following characteristics
1.Three start-up modes: the starting mode of the voltage slope can get the
maximum output torque, the maximum limit of the starting current, the maximum
starting torque of the load starting mode can be output
2.Parking mode: soft parking of the voltage slope, free parking
3.Programmable delay start mode, programmable interlocking control,
programmable fault contact output
4.Without phase requirement of input voltage
5.Start-up time, parking time can be programmed to modify programmable
changes
6.A variety of protection functions: over current, three-phase current imbalance,
overheating, lack of phase, motor overload and other protection
7.Dynamic fault memory function, easy to find fault cause, can record five fault
8.Can find the maximum starting current and maximum running current online
Standard:G14048.6-2008 5.5-600KW
Protection grade:IP20
Environment:Altitude less than 3000,vibration power device exceed 0.5 G
Anti-impulse:15kg/11ms
Temperature:-30°C~50°C
Humidity:less than95%, no condensation or water
Special function
YCQR2 series soft starter is suitable for AC 50Hz, 380V, 660V, and 5.5~600kw of the
squirrel cage motor
Starting mode:
1.Limited flow type: limit the starting current, reduce the starting voltage, arbitrary
adjustment, keyboard setting.
2.Voltage ramp type: the motor provides a smooth starting process, reducing the
impact of the starting current to grid, cut down the vibration and noise of the
equipment, and prolonging the life of the mechanical transmission.
3.Overload starting: can output the maximum starting torque
Parking mode:
a.free parking b. soft parking
Control mode : input:Passive switching signal
Output:Relay passive contact
