SB60型变频器矿用提升机调速系统四象限运行,回馈能量送回电网。用外端子控制多挡速,多挡频率转换、点动运行控制、起动时间、制动时间由外接开关的通断组合来实现。SB60变频器灵活设置起动时间和制动时间,起动和制动能平稳运行,提升机升、降速方式运行速度曲线成S形。
SB60 frequency converter mine hoist speed control system four quadrant operation, feedback energy back to the grid. Multi-speed control with external terminals, multi-block frequency conversion, jogging operation control, starting time, braking time by the external switch on and off combination to achieve. The SB60 frequency inverter can flexibly set the starting time and braking time, the starting and braking can run smoothly, and the lifting speed of the elevator can be increased. The running speed curve of the deceleration mode is S-shaped.
