Safely-Limited Position (Slp) - Siemens SINUMERIK Series Function Manual

Overview of Safety Integrated functions
2.3 Safety Integrated Extended Functions
Selecting and deselecting SDI
As soon as the inverter detects the selection of SDI via a fail-safe input, the following happens:
● You can also set a delay time, within which time you can ensure that the inverter moves in
the enabled (safe) direction.
● You can also set a tolerance, within which the inverter tolerates movement in the direction
that has not been enabled (safe).
● After the delay time has expired, the inverter monitors the direction of rotation of the motor.

Note
As an alternative to control via terminals, there is also an option to parameterize the SDI
without selection function. In this case, the SDI function is permanently active after POWER
ON.
