其主要特点:
1、机构紧凑、连接可靠,控制单元密封,控制板喷涂绝缘防腐层,高可靠性
2、耐高温,适应恶劣的工作环境。
3、高**性
① 起动时提前建立电机力矩,短时后制动器释放。
② 高速档回低速档时恰当利用反接力矩以防溜钩。
③ 特殊的**措施,不工作时,速度反馈线断路,控制器不能起动。运行中速度反馈线断路,控制器立即制动停机。
4、优越的控制性能
① 闭环控制使速度不因载荷变化而变化。平稳的控制减小对减速箱和电机的冲击。先电制动后机械制动,减小制动器磨损。
② 采用转子频率反馈为速度反馈。
③ 一种*简单、*可靠、*经济的反馈方法。
5、零电流换相或无触点换相,延长接触器寿命
6、容量范围大(控制器的标称电流),15A~2500A
7、结构合理,晶闸管单元与控制单元采用接插件连接,便于维修拆装。
8、液晶屏显示,可中英文切换,方便用户查看和设置参数。
9、带时钟功能,记录20条故障记录。
10、内置通讯智能芯片,支持PROFIBUS现场通讯总线协议,可与PLC及上位机通讯。
11、所有参数出厂时已设为默认值,实现现场免调试。
