This funcon moves the drive from a situaon that is blocking it ("Deadlock").
In the safety concept, this state is taken into consideraon as a special case for actuang an
a
xis connected. The encoders connected are not evaluated in a safety-oriented fashion.
DANGER!
In the RMS operang mode unexpected movements with an unexpected speed may occur.
In the RMS operang mode, the permissible moon limits of the axis may be violated.
▶
The use of the RMS funcon is exclusively permissible to release an axis from a "deadlock".
If possible, the OMS funcon should be used!
▶
In the RMS operang mode, exclusively the enable switch is eecve. Ensure, if necessary
b
y addional safety measures, that no persons can be endangered.
In the repair mode, the safety funcons are solely restricted to the parameteris-
able S
TO and SS1 stop funcons (without ramp monitoring) and the eecve-
ness of the enable switch.
DANGER!
With this funcon, all monitoring funcons are
deacvated.
The state of the facility is not monitored.
▶
Only use this funcon for a vercal axis with a brake on the load side.

SHOM status is reset. 4Safe homing (SHOM) ^ 428
Request of the repair mode
The repair mode is requested by the "ON state" on a safe input. The funcon must have been
assigned t
o the corresponding input by parameterisaon.
Only if no safe input is ulised, the funcon can be acvated via the safety bus.
Via the sa
fety bus, a data telegram with a corresponding content is sent to the
inverter, see safety bus .
