5.7.9 Using hardware enable
Reaction
Controller not enabled If the controller enable is not set (no ENABLE signal at the
controller interface and [HMI = off ] on the control panel):
If the hardware enable is missing, the Power" LED flashes.
The SFC−LACI can be parameterised, however, and records the
position of the drive.
Controller enabled If the controller enable is
set:
When the hardware enable is removed, the load voltage is
switched off.
Caution
If the drive is not under position control after the removal
of Hardware enable", this may cause injury to people and
material damage
If the hardware enable is removed during a current posi
tioning procedure, then the mass continues to move due
to inertia.
 With vertical or sloping drive mountings, the moving
mass will
then slide down.
Also note:
When the hardware enable is removed, the load voltage is
switched off immediately. However, several seconds can
pass before the SFC−LACI reports the error Load Power
Down" and a brake closes, if present.
