ABB XS321A-E GJR2252900R1 Pulse input module

DC bus connections are made using the drive and power supply front panel connections, located under the front panel screw mounted cover. Details of the supply and drive interconnections are given in Figure 2-6. In addition to the DC bus connections you will also need to connect the 24V DC controller voltage supply and the ribbon cable control bus. On the drive furthest from the power supply, the control bus will need to be terminated at connector X4, using the supplied termination plug. This applies even if only one drive is used.

Wiring Guidelines

 Proper grounding of electrical equipment is essential to ensure the safety of personnel. In general, all components and enclosures must be connected to earth ground to provide a low impedance path for ground fault or noise-induced currents. All earth ground connections must be continuous and permanent. A central earth busbar is recommended.Standard motor cables include the holding brake wiring and are made via the drive’s X1 screw block terminal, as shown in Figure 2-6. Details of motor cables are given in Appendix A.

Pre-Installation Test

 Before installing the drive in its final target application it is worth performing a preinstallation test of the drive’s functions to ensure the drive is working correctly and to become familiar with its operation and control. A recommended pre-installation test circuit for a single axis SV-M drive with a NMD power supply is shown in Figure 2-7. SV-M drives must be installed by competent personnel familiar with the installation, commissioning and operation of motion control equipment.
