SIMODRIVE POSMO A <strong>User</strong> <strong>Manual</strong> (POS1) – <strong>08</strong>.03 <strong>Edition</strong><br />
5 Description of the Functions<br />
5.5 SIMODRIVE POSMO A functions<br />
2. Assign digital input 1 to the function ”transfer value directly in the<br />
start byte (bit 7)”<br />
––> in SimoCom A under the tab ”Par” and entry ”Digital inputs/<br />
outputs”<br />
––> by setting SIMATIC S7 P0031 to 25<br />
3. Program the traversing block (e.g. block No. 9) as follows<br />
––> in the SimoCom A under the ”Par” tab and entry<br />
”Traversing blocks”<br />
––> select the ”relative” traversing type<br />
(set SIMATIC S7 P0<strong>08</strong>0:9 bit 0 to 0 via the SIMATIC S7<br />
––> enter the target position (max. distance to the cam)<br />
In this case, the sign of the distance specifies whether the<br />
signal is in the positive or negative traversing direction to<br />
the actual value.<br />
(if the drive moved through this distance, then the<br />
drive stops and changes to the following traversing block.)<br />
––> select ”Continue flying” block change enable<br />
(set SIMATIC S7 P0<strong>08</strong>0:9 bit 5 to 1 via the SIMATIC S7<br />
––> select PSW ”flying measurement: active” in the PSW selection<br />
box (set SIMATIC S7 P0<strong>08</strong>0:9 bit 10 to 1 via the SIMATIC S7<br />
4. Then program the following traversing block as follows (e.g. block<br />
No. 10)<br />
––> select the ”relative” traversing type<br />
(set SIMATIC S7 P0<strong>08</strong>0:10 bit 0 to 0 via the SIMATIC S7<br />
––> set position, velocity to 0<br />
(set P0<strong>08</strong>1:10 to 0; P0<strong>08</strong>2:10 to 0 via the SIMATIC S7)<br />
––> select ”continue flying” block change enable<br />
(set SIMATIC S7 P0<strong>08</strong>0:10 bit 5 to 1 via the SIMATIC S7<br />
––> in the selection box PSW check that ”SM start type” is in the<br />
default setting ”SM start type: wait” (bit=0)<br />
(set SIMATIC S7 P0<strong>08</strong>0:10 bit 7 to 0 via the SIMATIC S7<br />
––> in the selection box PSW, select ”flying measurement: active”<br />
(set SIMATIC S7 P0<strong>08</strong>0:10 bit 10 to 1 via the SIMATIC S7<br />
This means that a measurement is made if the cam is<br />
passed during the braking phase.<br />
––> SM/MM - set start bit 15 to 1<br />
(set P0<strong>08</strong>6:10 bit 15 to 1 via the SIMATIC S7)<br />
This means that the traversing block is only executed<br />
if the BERO/cam was actually reached.<br />
The program can be started under the ”Control” tab, entry ”Automatic”.<br />
The program with the number of the start block must be selected to do<br />
this.<br />
