Enables
Group diagnostics When group diagnostics is enabled, an
encoder error (ERR_ENCODER), no load
voltage (ERR_2L+) or a parameter
assignment error will result in a channel-
specific diagnostics.

Encoder signal
diagnostics
Encoder signals A, /A and B, /B or D, /D
are monitored for short circuit and wire
break at 5 V differential signals.
At incremental position encoders and non-
activated dosing operation monitoring of
the signal sequence is also carried out. A
simultaneous edge change at Signals A
and B causes an error.
At an SSI encoder monitoring of the frame
is carried out additionally (start bit and stop
bit)

Zero marker
diagnostics
At incremental encoders with 5 V
differential signals the zero marker signals
N, /N are monitored for short circuit and
wire break.
