Product Description

SINEE EM630 high-performance Closed-loop vector control Special VFD Inverter for tower crane   
•Closed-loop vector control; low-frequency large-torque stable operation: 0Hz/150% steady output of the rated torque to ensure stable operation of lifting equipment in the process of starting, lifting, and lowering. 
•Zero-servo function: With an encoder connected, the inverter can drive the motor to hold the full load in the air or to lower the full load at a controlled low speed when the brake fails, providing additional protection for lifting equipment. 
•Over-speed protection: With an encoder connected, the inverter can provide protection against parking or running at an excessive speed, so that any abnormality in speed and braking power during lifting can be timely identified to prevent hook slips. 
•Special control logic for brake: It controls the brake of lifting equipment to open and close in a reasonable time sequence so that safe operation of the system can be guaranteed and the service life of the braking system can be prolonged. 
•Wide voltage input range with automatic voltage stabilization: it can still meet the torque output requirement upon voltage drop of the power grid; 
•Wide speed control range: it can meet the requirements of lifting light loads at high speeds and lifting heavy loads at low speeds to improve the working efficiency of lifting equipment. 
•Tower crane slewing algorithm: it can ensure no shaking of the tower crane slewing mechanism during operation, reduce the risk of speed overshoot, reduce the current during slewing at variable frequencies, and improve the operating efficiency.
