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.
A simultaneous edge change at Signals A
and B causes an error.
Only the encoder signal A is evaluated.
This means that only a path change in the
positive direction is possible.
Selection of the output circuit of the
encoder for the signals A, B and N
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 DI1 digital input is a break or
make contact
Switch on the DI2 digital input is a break or
make contact
This parameter defines the relevant switch
or the combination of switch and zero mark.
