Configuring SSE
To configure the SSE function, set the FSO parameters listed below to appropriate
values using the Drive composer pro PC tool. See parameter groups
SSE on
page 417 and SBC on page 412 .
For more information on the SSE function, see page 106 .
Note: Always set the parameters related to the SSE function to have the correct trip
limit hit and fault reaction behavior. For example, the FSO module activates the SSE
function if an I/O failure occurs.

How to configure SSE with immediate STO
Example 1 (without an encoder): The figure below shows an example of the SSE
function with immediate STO set-up when an encoder is not used:
• drive STO is activated immediately after the SSE request
( SSE.13 SSE function = Immediate STO )
• automatic acknowledgement ( STO.02 STO acknowledgement = Automatic )
• redundant emergency stop button connected to input
( SSE.11 SSE input A = DI X113:1 & X114:1 )
• no outputs connected
• delay for restarting the drive: 1500 ms. This is the estimated time in which the
motor coasts to a stop from the maximum speed.
(
STO.14 Time to zero speed with STO and modoff = 1500 ms )
• no brake ( SBC.11 STO SBC usage = None ).
SSE.13 = Immediate STO
STO.14 = 1500 ms
