性能特点

控制系统采用H7四象限变频器和可编程控制技术，具有控制精度高、运行稳定、制动效果好、节能率高等特点。对传统的门、适合于桥式起重机所有电力拖动系统的控制柜配套和技术改造，使门、桥式起重机实现平稳操作，提高运行效率，改善超负荷作业，消除起制动冲击，减少电气维护，降低电能消耗，提高功率因数延长使用寿命等均可取得良好实效。同时该系统还具有过电流、过电压、欠电压和输入缺相保护，以及变频器超温、超载、超速、回馈制动单元过热、故障保护、电动机故障保护等，具有如下显著特点：

1、调速范围宽，可实现多种速度选择；

2、软启动、软停止的功能降低了机械传动冲击，可明显改善钢结构的承载性能，延长了起重机的使用寿命；

3、高集成度组件及高可靠性低压电器，有效解决原电气系统接线复杂问题，不仅降低了系统故障率，而且易维护；

4、电动机在零速时，能全力矩输出，即使制动器松动或失灵时，也不会出现重物下滑，确保系统安全可靠；

5、具有快速的动态响应，不会出现溜钩并真正实现“零速交叉”功能；

6、负荷重量测控仪并配以相应软件，起升速度可随负荷重量变化自切换，实现“轻载快速，重载慢速”的作业要求；
