This alarm occures when runnuing the spindle but not each time, this alarm occures also when manipulating the potentiometer in increasing the speed. Anybody knows the meaning of this alarm. Any help appreciate. Repbob.

Ekalavya Posts: 2964 Rating: (484)	Hello... Meaning of the alarm 27011:safely–reduced speed exceeded Reason: The axis has moved too quickly and faster than that specified in MD $MA_SAFE_VELO_LIMIT. When SBH/SG is active and for a 1–encoder system, the speed, that corresponds to the encoder limit frequency saved in MD SAFE_ENC_FREQ_LIMIT was exceeded. Remedy / Help: If no obvious operator error has occurred: Check the value entered into the MDs, check the SGEs: Was the correct safely–reduced speed selected? If the MDs and SGEs are o.k., check the machine for any damage and rectify Regards, Prakash
