Description

Allen Bradley 1394-AM04 is an axis module from the 1394 digital AC multi axis motion control system. This module is an A/B series module with an input voltage of 530/680 V DC and an output voltage of 310 V AC/390 V AC, three-phase, continuous output current of 4.5 Amps, peak current of 9 Amps, and continuous output power of 2.4 kW @ 310 V AC and 3 kW @ 390 V AC. Please note that when connecting and wiring power and signal lines on the machine or system, radiated noise from nearby relays (relay coils) should be equipped with surge suppressors, transformers, and other electronic devices can introduce drives into the motor or encoder for feedback, communication, or other sensitive low voltage signals. This can cause system failures and communication issues. All wire sizes in this manual are recommended to be the minimum size for the radiation noise level, wiring machine power supply, and signal wires, respectively, in the system module. Assuming the wire is MTW type copper wire (machine tool wire, 75 ° C, minimum), unless otherwise specified. Consult with national (or local) environmental conditions regarding electrical specifications, length, etc. Please consult your Allen Bradley sales representative for more information on shielding feedback, commands, and other protective covers that are independent of each other in order to minimize radiation and induced noise issues or grounding circuits, as well as connecting them to general machine or system grounding. Connect all shields to one grounding point. Please refer to the 1394 system in this chapter on grounding and the additional system signal insulation open shield (located in the speed command cable at the rotary transformer and servo driver) in Appendix B to avoid causing a grounding circuit. The inverter carrier frequency of EMRFI shielding 1394 is 5000 Hz. The carrier frequency generated by the output inverter switch sequence of the driver is 10000 Hz when measured on the motor. This can cause noise to enter the adjacent sensing device line. Axis Link provides a network (up to eight standards) for transmitting data between multiple nodes, allowing you to synchronize complex motion applications. For example, these nodes can be eight GMC system modules, one ALEC and seven GMC system modules, or a combination of other modules. AxisLink allows the use of a 1394 as the spindle for electronic transmission devices, cams, etc. on other systems. Using the expansion node option firmware version 3.5 (or later) in GML version 3.9.1 (or later), you can link up to 16 nodes. Connect the AxisLink cable to the JI using a three pin connector, as shown in Figure 4.12. The maximum end-to-end wiring configuration for daisy chains is 25 meters (82 feet). The minimum distance between AxisLink nodes is 0.9 meters (3 feet). Refer to Figures 4.7 and 4.8 for the location of the AxisLink connector. The GMC Turbo system provides AxisLink extension length options for applications that require longer AxisI.ink cable lengths. This “extended length” option allows users to support up to eight nodes for a maximum end-to-end cable length of 125 meters (410 feet) (provided by the user). To enable the ‘Extended Length’ option, set the GMC Turbo system module between the Flex I/O and AxisLink connectors located at the bottom of the switch. The switch is shown in Figure 4.7 and the switch settings are shown in Figure 4.14. The expansion node option allows users to support up to 16 nodes with a maximum end-to-end cable length of 25 meters (82 feet). This feature is enabled in GML version 3.9.1 (or higher) with firmware version 3.5 (or higher). Important note: If the ‘Extend Length’ option is enabled.
