Caution
An uncontrolled drive can cause injury to people and
material damage.

A logic 0 at the ENABLE input causes the power output
stage to be switched off. Under certain circumstances,
mass inertia or external forces can cause the drive to conĆ
tinue to move uncontrolled. Observe the instructions in
section 1.3 on the behaviour of the drive when ENABLE is
removed.
