Reset CDATA−NOUT
After a feeding process, the traverse path is backed with CDATA−REL−SEL = LOW (signal at
CDATA−NOUT). In the case of long traverse paths, this procedure takes an accordingly long time.
You can set the signal at CDATA−NOUT to 0 directly:
1. Set C1297 = 1.
2. Set CDATA−REL−SEL = LOW and CDATA−X−RESET = HIGH.
– The drive is disconnected from the CDATA function block, and the speed signal at
CDATA−NOUT is reset to 0.
