4-24 1394 Drive System Family
User-Supplied Input Fusing Specifications
The following section contains user-supplied input fusing specifications for the 1394 system and 1394
SERCOS interface system.
User-Supplied 24V Logic Input Power Specifications
The following section contains user-supplied 24V logic input power for the 1394 system and 1394 SERCOS
interface system.
Note: The power supply must be rated for 15A or greater inrush current upon power up.
Input Transformer Specifications for 24V Control Power
The following section contains 24V input transformer specifications for the 1394 system and 1394 SERCOS
interface system
.
Note: If the input volt-amperes is more than 350 VA, adjust the load regulation to make the transformer
leakage the same as or greater than the 250 VA transformer with 2% regulation.
