Posi- and synchronous operating
Disadvantages:
Limitation of the number (max. 10, after RS.422 specification)
-
- No guarantee of an EMC conform installation (adapter required for distribution) therefore, the second
variant is preferable:
Therefore the second variant is preferable:
- one MS-Repeater before each slave drive

Advantages:
- The incremental signals are processed. Thus, no limitation of the number of the connected slaves
- off-the-shelf cables available that guarantee EMC compliant assembly. Further information on availa-
ble components can be found at wow.keb.de => Service & Downloads
