报警功能 |
● 当 1 绿 1 红 闪烁时,表示闭环驱动器供电电压低;解决方法:检查闭环驱动器供电电压是否过低;
● 当 1 绿 2 红 闪烁时,表示闭环驱动器供电电压高;解决方法:检查闭环驱动器供电电压是否过高;
● 当 1 绿 3 红 闪烁时,表示闭环步进电机相位开路;解决方法:检查闭环步进电机接线是否错误;
● 当 1 绿 4 红 闪烁时,表示闭环步进电机相位过流;解决方法:检查闭环驱动器MOS管是否损坏或闭环步进电机是否损坏;
● 当 1 绿 5 红 闪烁时,表示闭环步进电机编码器故障;解决方法:检查闭环步进电机编码器是否接线正确和是否损坏;
● 当 1 绿 6 红 闪烁时,表示闭环步进电机编码器反馈位置超差;解决方法:检查闭环步进电机是否丢步;
● 当 1 绿 7 红 闪烁时,表示闭环驱动器其他故障;解决方法:寄回厂家检测;
以上报警功能启动时,步进电机失去自锁能力,若要回复正常工作,需要确认以上故障消除,然后重新上电,绿色电源指示灯常亮,驱动器回复正常。
▲ 注意:由于驱动器不具备电源正负极反接保护功能,因此上电前请再次确认电源正负极接线是否正确,否则电源正负极接反将导致烧坏驱动器中的保险管。
