The machine operating mode Setup Mode is activated when the guard is opened and the level at the inputs SETUPMODE_A and SETUPMODE_B is 1.
Take into account that the velocity of a movement in a multi-axis system can be greater than the velocities of the individual axes.
With the safety-related function SLS, the safety module eSM monitors set speed limits. The following conditions must be met:
The safety module eSM is in the eSM operating state 6 (Operation Enabled).
The level at the safety-related inputs GUARD_A and GUARD_B is 0 (guard open).
The level at the safety-related inputs SETUPMODE_A and SETUPMODE_B is 1 (machine operating mode Setup Mode).
The level at the safety-related inputs SETUPENABLE_A and SETUPENABLE_B is 1 (enabling device).
For SLS independent of the direction of movement, a common speed limit is set that applies to both positive and negative direction of movement.
For SLS dependent on the direction of movement, parameter values are set for the speed limits in positive direction and in negative direction of movement. This function is available for safety modules eSM with firmware version ≥1.01.

eSM speed limit for machine operating mode Setup Mode. This value sets the speed limit for monitoring in machine operating mode Setup Mode. Firmware version safety module eSM ≥V01.01: Parameter eSM_FuncSwitches Bit 0 = 0: Value = Monitored speed limit for positive and negative directions of movement. Parameter eSM_FuncSwitches Bit 0 = 1: Value = Monitored speed limit for positive direction of movement.

Movements are made in positive or in negative directions.
In the case of a rotary motors, direction of movement is defined in accordance with IEC 61800-7-204: Positive direction is when the motor shaft rotates clockwise as you look at the end of the protruding motor shaft.
If the monitored limit value is exceeded for the first time:
An error is detected
The safety module eSM requests a Quick Stop from the drive and monitors the Quick Stop ramp.
If the Quick Stop is executed properly, the safety-related function SOS is triggered.
If the Quick Stop is not executed properly, the safety-related function STO is triggered.
If the monitored limit value is exceeded again:
The safety-related function STO is triggered.
