7.8 Parameter List
Overview
Parameter List at Incremental Encoders with 5 V Differential Signals
Parameters Meaning Value range Default setting
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.
• Disable

Encoder signal
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.
• On
• Off
On
Zero marker
diagnostics
Zero marker signals N, /N are monitored for
short circuit and wire break.
• On
• Off
On
Axis
Dosing operation Only the encoder signals A and /A are
evaluated. This means that only a path
change in the positive direction is possible.
• Off
• On
Off
Reversal of the
direction of rotation
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.
• Off
• On
Off
Axis type Selection of linear axis without limits or
rotary axis with overrun/underrun with
encoder range
• Linear
• Rotary
Linear
End of rotary axis Only relevant for rotary axis type:
Underrun: 0 to end of rotary axis - 1
End of rotary axis - 1 to 0
1 - 16 777 215 36 000
