Configuration 393
Configuring mute times
WARNING!
The mute time increases the response time of the safety system.
This must be considered in the design of the safety system.
To minimize the effects of small transient variations in the speed measurement data,
you can fine-tune the operation of the safety functions with mute time parameters. For
the description of this feature, see
on page
How to determine values for mute time parameters
The suitable values for mute times can be determined by monitoring FSO speed
signals (
,
) with the Drive composer
pro tool. If possible, all transient situations within the whole speed range of the
application should be monitored. Based on the results, the mute times should be set
as short as possible. After the mute time parameters have been correctly set, safety
functions can be validated. You can check the motor speed for motor control from the
