6.5 Zero search modes
6.5.3 Set up the I/O’s for zero search
Important information : Each of the 8 pins can be defined as inputs or outputs. The ac-
tive digital input level for each input is also defined in the above screen. Furthermore, it
is possible to set up a filter for each input to avoid noise interfering with the program.
The inputs for Home, Negative Limit and Positive Limit are selected here.
6.5.4 Advanced settings
There are several ways to perform a Zero search:
- Start from both sides of the reference sensor in a system with limit switches without
having position limit problems.
- to go to the opposite side of the sensor and use this position as zero position.
- use a position limit as reference position. In this case the zero search position must be
be different from 0 or the motor enters passive mode.
- ignore the reference switch input and use the actual position or index pulse as zero
position before using the zero search position.
Zero search input setup
Negative limit input setup
Positive limit input setup
Make sure to set the selected
input(s) used for zero search
and limit switches as input
TT2478-01GB
Select this if it is desired to change
direction when the limit switch is met.
Otherwise the motor will make
a mechanical collision.
The final zero search point is found on
the «back side» of the zero search
sensor instead of the «front side»
Ignore the physical sensor connected
to an input but simply use the actual
position as zero (resets the actual
position counter) or look only for the
index pulse and use this as zero point
(if enabled in general zero search setup area)
