To set the monitor function use the parameter
• S-0-0391, Monitoring window feedback 2
If an error occurs, the error message F236 Excessive Position
Feedback Difference is generated.
Basic Operating Characteristics of the Position Feedback Monitor
The position feedback monitor compares the position feedback value of
the motor encoder with the optional encoder. If the deviation of both
position values is greater than S-0-0391, Monitoring window feedback
2, the error F236 Excessive Position Feedback Difference is
generated. As a result, the motor and optional encoder position status’
are cleared.
The position feedback value is only active if an optional encoder is
available and evaluated and if S-0-0391, Monitoring window feedback
2 is not parameterized with a 0.

Setting the Position Feedback Monitoring Window
The requirements for setting the position feedback value monitor are:
• All drive regulator loops must be set correctly.
• The axis mechanical system must be in its final form.
• The axis must be homed.
