ENABLE: I7 Controller and power end stage enable.
1−signal at the ENABLE input causes the controller and the
power end stage of the SFC−DC to be switched on.
0−signal at the ENABLE input causes the controller and the
power end stage of the SFC−DC to be switched off.
Please note
When the power end stage is switched off, the motor no
longer has current. This means that if the axis is installed
in an inclined or vertical position, the slide can move down
wards together with the work load.
As long as the logic voltage supply is not switched off, the
actual position is acquired even after the enable is switched
off. It is not necessary to carry out a new reference run.
