Locomotion interface
The Locomotion function indicates to the top module safety device when the robot is moving. Use this function to ensure that the top module is not powered while the robot is driving.
This function uses two output pins, where both pins deliver 0 VÂ when the robot is driving and 24 V when the robot is stopped. You can use this interface to make your top module behave differently depending on whether the robot is driving or not.
The interface is intended to be used to program the top module to go into a safe state when the robot is driving. For example, by engaging the brakes in any actuators that may result in injury to personnel.

Robot is driving
When the robot is driving, the safety PLC sends a 0 V signal to the top module through the Auxiliary safety function interface.

Robot is at standstill
When the robot is stopped, the signal becomes 24 V.
