報警功能 |
● 當 1 綠 1 紅 交替閃爍時,表示驅(qū)動器供電電壓低;解決方法:檢查驅(qū)動器供電電壓是否過低;
● 當 1 綠 2 紅 交替閃爍時,表示驅(qū)動器供電電壓高;解決方法:檢查驅(qū)動器供電電壓是否過高;
● 當 1 綠 3 紅 交替閃爍時,表示步進電機相位開路;解決方法:檢查步進電機接線是否錯誤;
● 當 1 綠 4 紅 交替閃爍時,表示步進電機相位過流;解決方法:檢查驅(qū)動器MOS管是否損壞或步進電機是否損壞;
● 當 1 綠 5 紅 交替閃爍時,表示驅(qū)動器其他故障;解決方法:寄回廠家檢測;
以上報警功能啟動時,步進電機失去自鎖能力,若要回復(fù)正常工作,需要確認以上故障消除,然后重新上電,綠色電源指示燈常亮,驅(qū)動器回復(fù)正常。
▲ 注意:由于驅(qū)動器不具備電源正負極反接保護功能,因此上電前請再次確認電源正負極接線是否正確,否則電源正負極接反將導(dǎo)致燒壞驅(qū)動器中的 保險管。
