Product Description

1. ZJT series inverter is controlled by V/f and vector control technology, with extensive application function module.
2. Sensorless vector control (SLVC), a built-in motor parameter testing procedures, can facilitate the use of more excellent performance of vector control.
3. V/f control. Through the whole frequency torque automatic compensation, compensation output torque, meet the need for high torque; Improves the dynamic response and motor control characteristics.
4. Proportional, integral and differential (PID) control function can be used for closed-loop control, constant pressure water supply process control.
5. Fast current limit (FCL) function, avoid undue tripping operation.
6. The built-in DC injection braking.
7. The acceleration / deceleration slope characteristics are with programmable smoothing function.
8. Automatic voltage regulator, when the input voltage changes, the output voltage is essentially constant, maintain a constant V/F value.
9. Speed tracking, inverter will automatically detect the rotate speed of the motor to make it smoothly to run into the input frequency setting.
10. Over voltage protection stall, the operation of inverter will limit the DC busbar voltage rise automatically.
11. Operation monitoring function including the output frequency, output current, rotational speed, load rate, accumulative total working time, DC busbar voltage and other parameters.
12. Fault and fault diagnosis monitoring function.
