Configuring Sse; How To Configure Sse With Immediate Sto - ABB FSO-21 User Manual

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
page 336 and SBC
For more information on the SSE function, see page 93.
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
• automatic acknowledgement
• redundant emergency stop button connected to input
(SSE.11 SSE input A
• 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
• no brake (SBC.11 STO SBC usage
