ABB DI650 3BHT300025R1 Digital Input

Input [X10] can be used to process incremental encoder signals as well as pulse direction signals, as generated by control boards for stepper motors. The input amplifier at the signal input is designed for the processing of differential signals as per interface standard RS422. Processing of other signals and levels (for example 5V single-ended or 24VHTL from a PLC) may be possible. Please contact your sales representative.The mentioned cable denominations refer to cables by Lapp. They have proven effective and are successfully used in many applications. However, similar cables from other manufacturers, for example Lütze or Helukabel, may also be used.When cabling the servo drives via the CAN bus, make sure to observe the following information and notes, to ensure a stable and interference-free system. Improper cabling may cause the CAN bus to malfunction which in turn can cause the servo drive to shut down with an error for safety reasons.

Cabling example for CAN-Bus 

 The individual nodes of a network are always connected in line, so that the CAN cable is looped through from servo drive to servo drive (see Figure 25) 

 On both ends of the CAN bus cable must be exactly one terminating resistor of 120 Ω +/- 5 %. All ARS 2100 SEseries servo drives are equipped with an integrated terminating resistor that can be activated/deactivated with the aid of the DIP switch “CAN TERM” that is located on the front panel (see Figure 8 and Figure 26) 

 Shielded cables with exactly two twisted pairs must be used for cabling  Use a twisted pair for the connection of CAN-H and CAN-L

 The cores of the other pair are used jointly for CAN-GND 

 The shield of the cable is led to the CAN shield connections for all nodes 

 For suitable and Metronix-recommended cables please refer to chapter 8.10.4 Cable type and design [X4]  We advise against the use of plug adaptors for CAN bus cabling. Should this be necessary nonetheless, make sure to use metal connector housings to connect the cable shield 

 In order to keep interferences as low as possible make sure that 

 Motor cables are not installed parallel to signal lines 

 Motor cables comply with Metronix specifications 

 Motor cables are properly shielded and grounded 

 For further information on interference-free CAN bus cabling, please refer to the Controller Area Network protocol specification, Version 2.0 by Robert Bosch GmbH, 1991

Cable type and design 

Interface cable for the USB interface, 4 cores, shielded and twisted. In order to set up a USB connection, it is mandatory to use a twisted and shielded (4-core) cable since, otherwise, the transmission may be subject to interferences. In addition, it must be ensured that the cable has a wave impedance of 90 Ω.
