Dangerous movements! Danger to personnel
from falling or dropping axes!
⇒ The optionally delivered motor holding brake or an
external brake controlled by the drive controller are
not sufficient to guarantee the safety of personnel!
Personnel safety must be achieved using higher-
⇒
ranking, fail-safe procedures:
Dangerous areas should be blocked off with fences
or grids.
Additionally secure vertical axes against falling or
sinking after switching off the motor power by, for
example:
- mechanically blocking the vertical axis,
- adding an external braking/catching/clamping
mechanism or
- providing sufficient counterbalance for the axis.
