EmailProduct Introduction
A drive with a docking function specially designed for the transformation of old elevators. Integrating frequency converter, brake module, and status indicator, it is convenient for on-site maintenance of equipment and minimizes the cost of frequency conversion transformation of construction elevator.
Features
1. Safe and reliable: The special brake logic control function, through the release frequency and the release current colleague to reach the brake, to ensure its safety and reliability.
2. High performance-price ratio: Compared with a complete set of inverter cabinets, the price is cheaper and the performance is equivalent.
3. Humanized design: No need to change the inverter parameters, as long as the wires are correctly connected, it can operate normally after turning on the machine.
4. The transformation is simple: no need to add deceleration limit devices, no replacement of the operating table; accurate landing can be achieved at any speed.
5. Convenient maintenance: The keyboard operator can display upper and lower limit, ascending and descending signals, which is convenient for system maintenance.
6. Extend the mechanical life: smooth operation, no impact, reduce the abrasion of the mechanical structure and vulnerable parts, prolong the use time of the motor and disc brake, and effectively increase the service life of the construction elevator.
Industrial Applications for AC70S Special Drive for Construction Elevator
