Two control modes: V/F control, Vector controlW/O PG,Vector control W/PG
Starting torque: 0.5Hz/150%(Vector control W/O PG);
Internal brake unit has been deployed, and the braking resister can be connected outside for a quick stop;
Five kinds of V/F control, which are constant torque V/F curve, One kind of customer defined V/F curve, 3 kinds of down torque curve (2.0/1.7/1.2 times the power).
Through PLC or internal control terminal, multi-speed control and PID control could be realized. And users could combine a variety of operating modes while it’s necessary;
Supporting multi-frequency deploy methods: digital setup, PID setup, analog quantity setup, and communication setup;
Supports starting and stopping DC brake;
PI500 is Equipped with jump frequency control, which prevents mechanical resonance and makes the system more stable and reliable;
PI500 has build-in PID in order to establish close-loop control system easily;
PI500 is designed with the central frequency switch function, which let the end user to fix the central frequency while it is necessary;
PI500 has been equipped with RS485 communication interface, which support MODBUS protocol with ASCII and RTU forms;
Working with water supply accessory to realize multiple-pump stable constaant pressure water supply function.
