(1)Equipped with a variety of monitoring, parameter editing, curve operation, oscilloscope and other functions, so that the debugging and maintenance of the inverter becomes more convenient. The drive replacement function, which automatically converts parameters from previous products, eliminates the need to set parameters duringreplacement of the inverter or when the inverter has fault.

(2)xLoaderTooL can upgrade inverter’s software online for quick and easy maintenance.

○ Support master-slave control

xPowerTool can monitor the inverter status in real time, configure the inverter parameters and control the inverter operation. Using a computer, you can manage several inverter parameters.

The inverter itself can be set as master or slave.

Set as master: You can select the synchronized reference value for reference of frequency, operating frequency or torque.

Set as slave: You can set whether the slave will follow the host’s command.

The inverter supports drooping control, which can realize load distribution control during drive of the same load by multiple motors.

○ Support standard brake logic and other safety shutdown functions Inverter demonstrates outstanding performance in construction lifting, tower crane, bridge and other applications.

○ Support speed limiting mode under a variety of torque control. The inverter can be used in many torque control circumstances.
Inverter demonstrates outstanding performance in construction l ifting, tower crane, bridge and other applications.
