TC760 tower crane inverter is a high-performance inverter launched by SINEE specially for lifting applications. It can be used in closed-loop lifting applications of tower cranes,
open-loop lifting applications of construction cranes, as well as in slewing and luffing applications of tower cranes. Factory values of related parameters may change with the
F20.00 lifting industry application macro selected.
TC760 tower crane inverter has the following features:
• Equipment of a built-in DC reactor (in case of an inverter of above 11kW) can reduce input current distortion, increase the power factor and promote the product reliability.
• 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 an 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 load at high speeds and lifting heavy load at low speeds to improve the working efficiency of lifting equipment.
