Performance

Wide voltage design: Voltage 380V ± 15%, and user can set over-voltage and under-voltage

Protecting values.

Convenient control: Control keyboard can be used in 100m away; Potentiometer on the keyboard to make the frequency output adjusting easier. Multiple indicator display the runing status.

Multi-point V/f curve setting: An intermediate point of the V / f value can be set freely, the control is more flexible, suitable for the special motor and non-motor control field.

Count timing: The new counting and timing functions with the input and output terminals working together, can achieve a variety of control functions, to reduce peripheral control parts.

High-speed pulse input: 50kHz high-speed pulse input interface can meet the control system demand.

Excellent control algorithm: Simple vector control can obtain more precise control effect by the motor parameter automatic detection. Full frequency segment automatic torque and slip compensation function suitable for mechanical processing industry.

Optimization of PWM modulation method: Optimization of PWM modulation method can make the output current waveform harmonics reduced and make the motor speed and torque ripple decreased at low speed.

Speed tracking start function: Start rotating motor smoothly, to avoid the current impact, especially effective on the fan and water pump.

Automatic energy-saving function: Automatic energy-saving function designed specifically for the fan and water pump type. When Motor is running at constant speed, the drive regulate the output voltage to minimum the motor power consumption.

Built-in PID feedback control function: The built-in PID control function can achieve precise closed-loop control on water supply control process.

Water supply one for two: Built-in two in one function can be used to control a variable frequency pump and a single-frequency pump in water supply.

Anti over voltage stall: According to the inverter bus voltage change, Automatically adjust the deceleration time when the motor decelerated to prevent over voltage occurs.

Anti over flow stall: According to the load inertia, automatically adjust the acceleration time when motor accelerated to keep motor running without tripping.

Over current frequency reduction: For transmission equipment or mixer equipment, when the load sudden change or motor stall, our drive can effectively restrain over current faults occur.
