1.2 Characteristics of the 1P 241
– The 1P 241 acquires position–based signals.
—
The 1P 241 provides two independent channels for one each position decoder with a maximum
of 16 tracks. Single channel operation, however, with 32 tracks can also be selected.
—
Incremental or absolute encoders can be connected via encoder matching modules (the sup-
ply voltage for these encoders can also be provided by the 1P 241).
—
Actual values can be read at any time with an S5 command.
—
A cam–operated master controller is electronically imitated in the 1P 241. This means that the
actual values are continuously compared with the initial and the end track setpoints and the
corresponding track identifier bits are set.
– The
1P 241 transfers these track identifier bits to the programmable controller (e.g., via a stan-
dard function block).
—
The track identifier bits are furnished in a way that allows them to be directly scanned and linked
in the control program (e.g., by an end switch).
– Hardware or software synchronization is available for incremental encoders.
– Each channel can be used for linear axis operation or for rotary axis operation.
