Combined inverter and braking module, no external brake unit required to build a tower crane control system.
When the actual running speed is faster than 115% of rated speed, it will send out brake signal to realize emergency brake immediately.
This feature will be activated instantly when the motor rotates but the inverter is in standby status. It is designed to provide maximum protection to the whole tower crane system.
By using AC80T, it can make tower crane lift at high speed in light load or empty hook status. It greatly improves the efficiency.
In the status of brake closed, press button to activate this feature. Please set the output torque to 180% of rated torque and check the motor speed. In this way, you can check whether the brake adjustment is appropriate or not.
The port can be used for satellite positioning and remote control (based on the management platform). It supports remote locking and unlocking function.
This function is achieved by the loose current frequency, brake release time, brake closing time and more. It ensures the safety and reliability of the whole system.
