Support ABZ interface

Sine wave output, support position, speed, torque control applications.

Speed PID closed-loop control, low speed torque, built-in model tracking, accurate variable estimation, high dynamic response.

High bandwidth, high rigidity, high response, forced convergence.

The acceleration and deceleration time can be set by the software to achieve smooth and soft operation.

The drive itself has low dissipation, high efficiency and low temperature rise, so it is small in size and easy to install.

Support 485 bus, IO port multiple input mode, set by software.

Enable,, direction, polarity of IO input signal can be set by software.

Multiple perfect protection functions.

IIT current limiting protection function to prevent the motor from blocking damage.

Built-in brake resistance and control circuit (optional), for consumption of renewable energy, prevent overvoltage.

Support different applications, dynamic response to the driver can be customized.

Support function depth customization, special machine application.

Enhanced cooling mode

(1) drive and reliable working temperature to normal within 60 ℃, the motor working temperature is 70 ℃

(2) when installing the driver, please install it vertically on the side, so that the radiator surface can form strong convection with the air, and when necessary, install a fan near the radiator to dissipate heat compulsorily, so as to ensure that the driver can work reliably within the reliable operating temperature range.

System wiring diagram


Wiring precautions

(1) do not directly connect the ac 220V power supply to the drive power input terminal.

(2) do not connect the power supply to the wrong side. The drive can withstand up to 50A reverse current. Exceeding this value will damage the drive.

(3) do not connect the power supply to the motor output end, otherwise the internal power device of the driver will be damaged.

(4) ensure that the motor phase sequence is connected to the motor output end of the driver. The disordered phase sequence may trigger an alarm or damage the motor and driver.

Power supply requirement

(1) the power supply voltage shall be between dc20-60v, and +/-20% network voltage fluctuation shall be considered if the transformer is rectified for power supply

(2) for stable and reliable operation, the power supply current should be greater than the maximum output current of the driver.

(3) switch voltage regulator power supply should pay attention to the overvoltage protection mode of power supply. Under the condition of fast deceleration with load, the motor will feed energy back to the power supply and cause voltage rise.
