All drives, apart from the P100, may also be mounted with the heatsink protruding through the mounting surface as shown in Figure 2-5. This has the advantage of allowing heat dissipated by the drive to be lost externally - preventing heat build-up within equipment cabinets.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.
SV-M Drive Main Connections
All drive types will require DC bus connections from either the NMD10 or NMD20 power supplies as well as the independent 24V DC power supply connection. 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.
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.
