Meaning
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 signals A, /A and B, /B are
monitored for short circuit and wire break.
In addition the signal sequence is
monitored. A simultaneous edge change at
Signals A and B causes an error.
Zero marker signals N, /N are monitored for
short circuit and wire break.
Only the encoder signals A and /A are
evaluated. This means that only a path
change in the positive direction is possible.
Adjustment of the direction of rotation of the
encoder A reversal of the direction of
rotation is only possible if no dosing
operation is set.
Selection of linear axis without limits or
rotary axis with overrun/underrun with
encoder range
Only relevant for rotary axis type:
Underrun: 0 to end of rotary axis - 1
End of rotary axis - 1 to 0
Switch on the DI0 digital input is a break or

make contact
Switch on the DI2 digital input is a break or
