Torque boost

Automatic torque boost. Manual torque boost 0.1%~30.0%

V/F curve

Five modes: Straight-line, Multi-points, Square V/F, V/F separation, V/F Semi-separation

V/F Separation

Two modes: complete separation, semi-separation

Ramp mode

Straight-line ramp and S-curve ramp.

Four kinds of acceleration/deceleration time with the range of 0.0–6500.0s

DC injection braking

DC braking frequency: 0.00Hz~maximum, braking time: 0.0s~36.0s.

Braking action current value:0.0%~100.0%

Jog control

Jog frequency: 0.00Hz~50.00Hz

Jog acceleration and deceleration tome:0.0s~6500.0s

Simple PLC, multistage speed operation

It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.

Built-in PID

It can keep constant output voltage automatically when the mains voltage changes.

Automatic voltage regulation(AVR)

Automatically maintain a constant output voltage when grid voltage changes.

Over voltage/Over current loss of speed control

Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage

Rapid current limit

Minimizing over-current fault and protect the normal operation of converter.

Torque limit and control

"Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip.

Closed-loop vector mode torque control can be achieved.

Installation Precautions


◆ Install the inverter on a non-combustible object such as metal to prevent fire.

◆ Keep flammable materials away from the inverter, otherwise there is a danger of fire.

◆ Do not install the inverter in a flammable or explosive environment, otherwise there is a danger of explosion.

◆ It is strictly forbidden to disassemble and modify the inverter privately, otherwise the consequences will be at your own risk.

◆ Wiring must be performed by a qualified technician to avoid the risk of electric shock.

◆ Do not open the cover or perform wiring work while the inverter is powered.

◆The cover must be covered before the inverter is energized, otherwise there is danger of electric shock and explosion.

◆For inverters that have been stored for more than 2 years, the voltage should be gradually increased by the voltage regulator before power-on, otherwise there is danger of electric shock or explosion.

◆ Do not touch the terminals by hand when power is on, otherwise there is danger of electric shock.

◆ Do not operate the inverter with wet hands, otherwise there is danger of electric shock.

◆ The maintenance operation can only be performed after the power is turned off for ten minutes. At this time, the indicator of the power supply is completely extinguished or the positive and negative bus voltages (P, N) are below 25V, otherwise there is danger of electric shock.

◆ Maintenance operations such as replacement parts must be carried out by professional technicians. It is strictly forbidden to leave metal objects such as wires or screws in the machine, otherwise there is a risk of fire.

◆ After the inverter is replaced with the new control board, the relevant parameters must be set correctly before its operating.

◆ Don’t connect the output terminals U, V, W of the inverter to the AC power supply.
