One of these points must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar.

  • Page 18: Protective Devices

    4.3 Protective Devices Recommended fuse sizes are based on the following: 115% of maximum continuous current for time delay. 150% of maximum continuous current for Fast or Very Fast action. Note: These recommendations do not consider harmonic currents or ambient temperatures greater than 45°C. Be sure a suitable input power protection device is installed.

  • Page 19: Optional Dynamic Brake Hardware Size

    Short cable runs are usually trouble free but fault-monitoring circuitry can produce numerous faults when long cables are used. Refer to Table 4-1 for maximum cable lengths. Baldor recommends adding an optional load reactor to the output of the control. The load reactor and/or common mode choke should be placed in close physical proximity to the control.

    C.1 CE Declaration of Conformity Baldor indicates that the products are only components and not ready for immediate or instant use within the meaning of “Safety law of appliance”, “EMC Law” or “Machine directive”. The final mode of operation is defined only after installation into the user’s equipment.

    3. The responsibility of CE mark compliance rests entirely with the party who offers the end system for sale (such as an OEM or system integrator). Baldor products which meet the EMC directive requirements are indicated with a “CE” mark. A signed CE declaration of conformity is provided in this section.

  • Page 55: Emc Wiring Technique

    CONTROLLER (Exception: Analog Command Signal). GROUNDING (EARTH) For safety reasons (VDE0160), all Baldor components must be connected to ground with a separate wire. The diameter of the wire must be at minimum AWG#6 (10mm Ground connections (dashed lines) must be made from the central ground to the regen resistor enclosure and from the central ground to the Shared Power Supply.
  • Page 56 A) All metal conducting parts of the enclosure must be electrically connected to the back plane. These connections should be made with a grounding strap from each element to a central grounding point. [1] B) Keep the power wiring (motor and power cable) and control wiring separated. If these wires must cross, be sure they cross at 90 degrees to minimize noise due to induction.

  • Page 59: Rs485/Modbus Protocol

    The VS1MX AC Drive is supplied with imbedded RS-485 communications that supports the Modbus-R TU protocol. This allows the user to set up a multi-drop communications network between multiple VS1MX drives and a PLC or host computer without the requirement of option boards for the drives. This is a master-slave architecture where the master (e.g. PLC) can monitor and control multiple VS1MX drives on the same network with other Modbus-RTU slaves.
