3−169
l
EDSVS9332K−EXT EN 4.0
Please see figures Fig. 3−129 and Fig. 3−130 for the interconnections of master and slave.
Differences to EXTPOL1:
l In the master only the X position (CDATA−X−POS) is sent
l The slave just receives the X position
Settings
l Code C1379
– Use C1379 to adapt the number of extrapolation cycles per ms to the cycle time of the bus.
STOP!
This function does not replace the monitoring of the bus system. The bus system should be
monitored with a "toggle bit".
Tip!
If, for instance, the transfer cycle is max. 5 ms, set at least 6 ms in C1379.
After the time set has been exceeded, the input EXTPOL2−PHIN is directly connected to the output
EXTPOL2−PHOUT. Only when new positions are detected at the input, the extrapolation restarts.
