Note: When an incremental encoder with square-wave signals is
used, the signals are not monitored.
Example:
Ucos = -6.5V
Usin = 6.5V
()
pointer length = - 6.5V + 6.5V » 9.2V

Remedy:
1. Check the measuring system cable.
1. Check the measuring system.
2. In the case of linear measuring systems, check the mounting of
the measuring head.
F245 Encoder 2 failure: quadrant error
The evaluation of the additional optional encoder (encoder 2) is active. In
the evaluation of the sinusoidal input signals of the optional encoder, a
plausibility check is performed between these signals and the counter fed
by these signals. Doing this, an error has been encountered.
Cause:
1. Defective encoder cable
2. Disruptive electro-magnetic interference on the encoder cable
3. Defective encoder interface
