No functional Safety!
Serious injury could result when the load is not properly blocked. This function does not
ensure functional safety.
Functional safety, e.g. with hanging load (vertical axes), requires an additional brake.
The Hardware Enable does not initiate a controlled stop but switches off the power stage
immediately.
Set parameter AXIS#.MOTOR.BRAKEIMM to 1 with vertical axes, to apply the brake
immediately after faults or Hardware Disable.
