ABB FSO-21 - How to Configure Mute Time for Monitoring Start

Configuration 399
 How to configure mute time for monitoring start
Example: The start of SLS monitoring in the SLS1 function
In this example, SLS1 function is requested from a higher speed than the SLS trip
limit.
• With an encoder: parameter FSOGEN.33 Monitoring start delay = 20 ms
• Without an encoder: parameter FSOGEN.31 Transient mute time = 20 ms.
1 SLS request activated
2 Safe speed in the middle of SLS and SLS trip limits
3 SLS monitoring started. SLS indication activates (SLSx.15, SLSx.16).
