Setting functions
8.6 Basic positioner and position control
Procedure: Fixed stop using maximum following error
To set "Travel to fixed stop" using maximum following error, proceed as follows:
1. Select "Fixed stop using maximum following error":
2. Set the following error that the inverter uses to detect the fixed stop.
3. Set the tolerance.
After the fixed stop is detected, the inverter monitors the actual position of the axis. If the
actual position value changes by more than this distance, then the converter stops the
axis and outputs fault F07484. Therefore, the converter detects that the fixed stop has
"broken away"
You have now set "Travel to fixed stop" using maximum following error.
