Jogging control

In some applications, the frequency converter needs to run at low speed for a short period of time to facilitate testing the condition of the equipment

Torque control

Torque control is possible when vector controlled

Simple PLC, multi-terminal speed

16 speed operation is achieved through the control terminal

Built-in PID

It can be easily formed as a closed-loop control system

Virtual IO

8 virtual VDI/VDO and 3 AI DI for simple logic control

Overvoltage and overcurrent stall control

Automatic current and voltage limit during operation to prevent frequent overcurrent and overvoltage tripping

DC braking

Start the DC brake and stop the DC brake

Pre-excitation

The motor is pre-excited when the frequency converter is started, and the magnetic field is established inside the motor, which can effectively improve the torque characteristics during the start of the motor

Overexcitation

It can effectively suppress the rise of bus voltage during the deceleration process, avoid frequent overvoltage faults, and realize rapid braking to meet the rapid stop of power outages

RPM tracking

Both asynchronous and synchronous machines support speed tracking function; Vector control and V/F control both support speed tracking function

Protection function

Overvoltage suppression, undervoltage suppression, V/F overcurrent suppression, ground short circuit protection, phase loss protection, speed deviation detection, overvoltage protection, overcurrent protection, undervoltage protection, overload protection, overtemperature protection, start protection, bus undervoltage point setting, bus overvoltage point setting, etc
