Connection and installation of front modules

Always attach the option to the unit with the screw that is included in the delivery. For size 0, mount the spacer bolt first. The bolt is already installed in sizes 1 and higher. The screw connection ensures a high-frequency EMC connection between the basic unit and the option.

The DC 24 V potential of X46:7 is identical to X12:8 of the basic unit. All GND terminals of the unit are connected to each other and to PE.

  • Use a 4-core twisted and shielded copper cable (data transmission cable with braided copper shield). The cable must meet the following specifications:
    • Cable cross section 0.25 – 0.75 mm2 (AWG23 – AWG18)
    • Cable resistance 120 Ω at 1 MHz
    • Capacitance per unit length ≤ 40 pF/m at 1 kHz

Suitable cables are CAN bus cables or DeviceNet cables.

Connecting the shield

  • Connect the shield to the electronics shield clamp on the inverter or master controller and make sure it is connected over a wide area at both ends.
  • There is no need for a ground connection between MOVITRAC® B and gateways, or MOVITRAC® B and MOVITRAC® B with shielded cables. A 2-core cable is permitted in this case.
  • When connecting MOVIDRIVE® B and MOVITRAC® B, be aware that the electrical isolation is eliminated between the reference potential DGND and ground in MOVIDRIVE® B.

 

  • NOTICE Potential shift
  • Possible consequences include malfunctions that could lead to irreparable damage to the unit.
    • There must not be any potential shift between the connected units. Take appropriate measures to avoid potential shift, such as connecting the unit ground connectors using a separate cable.

 

INFORMATION

The FIO21B and FSE24B front modules require a 24 V supply. If there is no external voltage supply, you must not switch off parameter P808 24VIO auxiliary voltage output.
