If fatal errors occur in the drive system, the motor can no longer be
stopped by braking. The motor becomes torque-free and coasts to a
standstill.
An example of a fatal error is when the bridge fuse blows. (see function
description).

or death!

sible measures to be taken to prevent access by un-
authorized persons:
- protective fence
- protective railing
- protective covering
- light barrier
⇒ Fences and coverings should be strong enough to
withstand the maximum possible momentum.
If other errors occur, such as "excess amplifier temperature", the motor
can be stopped (see function description).
As a result of the high capacitive leakage currents via the cable insulation,
it is not possible to install a GFCB device in the input power line
(compliant to DIN VDE 0160, section 6.5).
Thus, protection against indirect contact must be achieved by other
means.
The drive system components have a protective grounded housing. This
makes protection against indirect contact possible by grounding.
