Displaying the Status of the Run
You can read the status of the run from the feedback interface from byte 0, bits 5 and 6. This
status display is possible in the reference point run and absolute and relative positioning
MODEs.

Effect of the Hardware Limit Switches
The two digital inputs (DI0 and DI1) are evaluated by the 1PosInc/Analog as hardware limit
switches:
● DI0 is the minus limit switch and limits the operating range in the minus direction.
● DI1 is the plus limit switch and limits the operating range in the plus direction.
You can assign parameters to the hardware limit switches separately as break contacts or
make contacts.
The hardware limit switches are evaluated with linear axes and rotary axes.
This enables you to move away from a hardware limit switch without additional error
acknowledgment by moving in the other direction if you reach or overrun a hardware limit
switch.
Only the hardware limit switch that lies in the direction in which the drive is being moved is
evaluated.
The current signal level of the digital inputs is displayed in the feedback interface, delayed by
the update rate.
