Single-axis controllers Control terminals 4 4.7 System bus CAN on board The controller features an integrated CANopen system bus interface to exchange process data and parameter values between different nodes and to connect further modules as e.g. distributed terminals, operator and input devices (”HMIs”) and external control units. Note! The X1 connection is not available in the ”StateLine” design. 24 V supply The controller generates the supply voltage for the control electronics from the mains voltage. As an option, the supply voltage can be fed by a mains-independent 24 V source. Thus, the control functions remain active even after power is removed. Warnings!
In UL-approved systems the fuse of the 24 V supply must not exceed 4 A. 4.7-3 EDS94SPP101 EN 3.1-04/2007 Terminal X1 Labelling Description 9400SSP000X1 Pin 2 CAN-LOW Pin 3 CAN-GND Pin 7 CAN-HIGH (Housing) CAN-Shield Electrical data 24 V Rated voltage 24 V According to IEC 61131-2 Voltage range 19.2 ... 28.8 V Residual ripple max. ± 5 % Current consumption Approx. 1.2 A during operation Max. 3 A starting current for 100 ms Fuse Circuit breaker with tripping characteristic B or C, Standard blade-type fuses Looping through Max. 12 devices with 2.5 mm2 Fusing: 16/15 A Max. 8 devices with 1.5 mm2 Fusing: 10/10 A Connectable cross-sections See terminal data Cable length Max. 5 m
