SJ700 Series Dotech

Use the convenient high-performance inverter with a simple adjustment 
CRANES, EXTRUDER, LIFTS suitable for 
high torque, high-performance, high-function inverter 

3-phase 200V class: 0.4 ~ 55kW / 3-phase 400v grade: 0.75 ~ 400kW

Easy to use, high-performance inverter with a simple adjustment

1. powerful driving achieve

the same torque more than 200% in the notice 0.3HZ
applicable to the lift system 0Hz sensorless vector control,
position control


2. trip inhibition achieved stable operation


over-current and over-voltage suppression
deceleration of DC BUS AVR function


3. the parent device does not need to program operation function


Simple operation sequence realized
cranes or overdrive automatic operation suitable for the condition of the load conveyor, etc. can also
have a parent device can be simplified, and cost savings in the space around the circuit of the control panel contributions


4. the peripheral circuits built into inverter


noise reduction that occurs in EMC noise filter to the inverter with standard
built-in (22kW or less) of the regenerative braking circuit (BRD)
micro-surge voltage suppression


5. maintenance simple


extra cooling to the removable structure fan, a smoothing capacitor, maintenance is more ease of control terminal
design life 10 nyeon achieved by adopting a long-life components
, further extending the oN / OFF control to the service life of the cooling fan can
condenser, aging degree, the temperature of the cooling fan and the motor of the cooling fan monitors can rise
lifespan notice enhanced ease of maintenance by the signal


6. simple parameter setting

data comparison functions, user-selectable features, ease of operation there are features such as the default mode


7. communications, network compatible

RS-485 Modbus-RTU to corresponding port as standard
option by the substrate can correspond to DeviceNet, PROFIBUS, CC-Link
Oper Network - available


8 global response


standards corresponding to international standards (UL, cUL, CE, C -Tick)
sink / source logic corresponds to the standard
width wide supply voltage specifications


9. environmental consideration


EU RoHS Directive correspondence
in improving environmental performance
