Parameter List at Incremental Encoders with 24 V 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
A simultaneous edge change at Signals A
and B causes an error.
• On
• Off
On
Axis
Dosing operation Only the encoder signal A is evaluated.
This means that only a path change in the
positive direction is possible.
• Off
• On
Off
Sensor Selection of the output circuit of the
encoder for the signals A, B and N
• Current-sourcing
switch, push-pull
• Mono-switch
Current-sourcing
switch, push-pull
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

Reference point run and evaluation of the reference signal
Reference signal This parameter defines the relevant switch
or the combination of switch and zero mark.
• Reference switch and
zero mark
• Reference switch
• Zero mark
Reference switch and
zero mark
Reference switch Relevant in the case of reference signal:
• Reference switch and zero mark
• Reference switch
This parameter defines the referencing
direction in which the switch must be
traversed.
• Reduction cam towards
minus
• Reduction cam towards
plus
• Minus limit switch
