Positioning Operating mode
8.1 Function Description
Synchronization
8-2
In this operating mode, the CM35 supports controlled positioning with a
switch- - off point.
An incremental encoder is connected to acquire the position. The encoder
pulses are acquired by the module with the correct sign in the traversing
range from –2,147,483,648 to +2,147,483,647.
Two digital outputs which are addressed by the CM35 based on direction are
available for each of the four channels.
Traversing Range Lower Limit of Traversing
32 bits -2,147,483,648 increments
Note
When the position is no longer in the traversing range, the actual value jumps
from positive to negative or from negative to positive. You must ensure that the
traversing path is located within the traversing range limits.
To synchronize actual value acquisition, you can execute ²set actual value²
with the user program. Move the axis to a position whose coordinate is
known. Transfer this coordinate to the module with ²set actual value.² The
specified value is accepted as the current actual value.
Note
The conversion of the incremental value to a length value and vice versa
must be handled by the user program.
