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 D, /D are checked for short
circuit and wire break. Monitoring of the
frame is carried out additionally (start bit
and stop bit)
Selection of single-turn encoder (SSI 13 bit)
or multiturn encoder (SSI 25 bit)
Only relevant in the case of multiturn
encoders. In the case of single-turn
encoders, the 1PosU sets the number of
rotations to 1.
Adjustment of the direction of rotation of the
encoder
Selection of linear axis without limits or
rotary axis with overrun/underrun with
encoder range
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
