Material damages and personal injuries by the drop of a hanging axis
When the servo system is used as a hanging axis, the axis will drop if the positive and negative poles of the 24 V power
supply are connected inversely. Unexpected drop of the hanging axis may cause material damages and personal injuries.
Make sure that the 24 V power supply is correctly connected.
Material damages and personal injuries by the drop of a hanging axis
It is not allowed to use the STO with a hanging axis because the axis may drop. Unexpected drop of the hanging axis may
cause material damages and personal injuries.
