Interaction with EPOS

Since the function SS2 – with its setpoint-independent braking – is not suitable for use with
EPOS, the Safe Operating Stop (SOS) function can be used with delay.
On selection of SOS, the EPOS function "intermediate stop" (p2640 = 0) ensures that EPOS
is able to stop the drive in its tracks and then keep it under control in this state before the
SOS becomes active. The maximum necessary braking time (from p2573 and p2645) must
then be entered in the delay time for SLS/SOS (p9551) with a safety margin: This ensures
that the drive is at a standstill before SOS is active.
To do this, proceed as follows:
1. Connect the EPOS function "intermediate stop" (p2640) with the control signal "Deselect
SOS" (r9720.3).
2. Enter the maximum necessary EPOS braking time (depending on the values set in p2573
and p2645) with a safety margin (approx. +5%) in the SOS delay time (p9551).
Since the STOP C stop response – with its setpoint-independent braking – is not suitable for
use with EPOS, the Safe Operating Stop (SOS) function can be used with delay.
On selection of SOS, the EPOS function "intermediate stop" (p2640 = 0) ensures that EPOS
is able to stop the drive in its tracks and then keep it under control in this state before the
SOS becomes active. The maximum required braking time (from p2573 and p2645) must
then be entered in the "Transition time STOP D to SOS" (p9553) with a small safety margin:
This ensures that the drive is at a standstill before SOS is active.
To do this, proceed as follows:
1. Parameterize "STOP D" as stop response.
2. Connect the EPOS function "intermediate stop" (p2640) with the control signal "Deselect
SOS" (r9720.3).
3. Enter the maximum required EPOS braking time (depending on the values set in p2573
and p2645) with a safety margin (approx. +5%) in the "Transition time STOP D to SOS"
(p9553).
