Repair mode select (RMS)
This function moves the drive from a situation that is blocking it ("Deadlock").
In the safety concept, this state is taken into consideration as a special case for actuating an
axis connected. The encoders connected are not evaluated in a safety-oriented fashion.
DANGER!
In the RMS operating mode unexpected movements with an unexpected speed may occur.
In the RMS operating mode, the permissible motion limits of the axis may be violated.
▶
The use of the RMS function is exclusively permissible to release an axis from a "deadlock".
If possible, the OMS function should be used!
▶
In the RMS operating mode, exclusively the enable switch is effective. Ensure, if necessary
by additional safety measures, that no persons can be endangered.
In the repair mode, the safety functions are solely restricted to the parameteris-
able STO and SS1 stop functions (without ramp monitoring) and the effective-
ness of the enable switch.
DANGER!
With this function, all monitoring functions are deactivated.
The state of the facility is not monitored.
▶
Only use this function for a vertical axis with a brake on the load side.

In the repair mode, speed functions and absolute position functions are deactivated. The
SHOM status is reset.
Request of the repair mode
The repair mode is requested by the "ON state" on a safe input. The function must have been
assigned to the corresponding input by parameterisation.
Only if no safe input is utilised, the function can be activated via the safety bus.
Via the safety bus, a data telegram with a corresponding content is sent to the
inverter, see safety bus .
