Ø Technical specifications

Ø Descripution

The Allen-Bradley 1394C-AM04 is a multi-axis module which belongs to series C in the 1394 family. Its specifications are like those of other multi-axis modules and its peak power is 3 kW. The continuous output current (RMS) of this module is 4.5 Amps, but within a second, the peak current can reach 9 Amps. The 1394C**-**AM04’s nominal input voltage is 530 to 680 Volts DC and its capacitance is the same as the 1394C-AM03 at a rate of 110 microFarad. It weighs 5 kilograms and there is a heatsink inside its cabinet.

The 1394C-AM04 has a slide-and-lock feature that makes it easy to modify the wiring. Use caution when connecting and routing power or signal wiring on a system. Radiated noise from nearby electronic drives can interfere with feedback, communications, or other sensitive low-voltage signals. This prevents the 1394C-AM04 from operating successfully. Use shielding on the cables to minimize radiated noise, and do not forget to connect all shields to a single ground point. Refer to the manual for further information. Be sure to insulate the open-ended shields (resolver feedback cable at the resolver and velocity command cable at the servo drive) to avoid ground loops.
