  • Page 7: Safety Instructions

    Safety instructions While in operation, inverter surfaces can be conductive, uninsulated, sometimes also moving or rotating, and hot – depending on the degree to which they are protected. This means that a frequency inverter drive can endanger human life. To prevent serious physical injury or considerable material damage, only qualified persons familiar with electrical drive equipment may work on the equipment.
  • Page 8 The inverter are to be protected against unauthorised stress. In particular, components may not be bent and/or insulation distances changed during transport and use. Inverters contain electrostatically endangered components that can easily be damaged when incorrectly handled. Electrical components may not be mechanically damaged or destroyed.

  • Page 9: Model And Accessories

    Model and accessories General The standard VF1000S model is denoted by the type designation only. Versions other than the standard are denoted by the addition of model codes to the type designation. Each model code has a particular meaning – see inverter models. Model codes are also used for inverters that are not in accordance with the list.

  • Page 25: Installation

    Installation General: The location for installation must be free from conducting or corrosive materials and also free from humidity. Frequency inverters are normally housed in cabinets with external air throughflow. They are attached to a mounting board with four M4 screws. It is essential that the minimum distances above and below the unit are observed to avoid heat build-up.

The certified EMC test on the immunity to interference of the inverters was carried out under laboratory conditions in accordance with prEN 50082-2/01.93.

  • Page 30: Power Connections

    Power connections 2.3.1 Mains connection General Inverters must be connected to the mains power supply in accordance with the VDE regulations such that they can be isolated from the mains at any time using appropriate means of isolation such as a master switch. Wait 2 mins after See also connection plan.

  • Page 31: Motor Connection

    2.3.2 Motor connection General Standard three-phase motors in the range up to 4 kW are available according to IEC 34 for various mains supplies in Delta (3 x 230 V) and in Star (3 x 400 V) formats. Three-phase standard motors for 110 V three-phase mains supply are generally required in non-European countries (e.G.

  • Page 32: Length Of Motor Cable

    2.3.3 Length of motor cable The motor cable may be no longer than the length given in the Power table, as longer leads with higher conduction capacities (especially screened leads) are at mains voltage. Higher lead capacities give rise to a high leakage current that switches off the inverter.

  • Page 33: Braking Chopper Connection

    2.3.5 Braking chopper connection General If the rotor rpm is higher than the corresponding stator rpm, the motor returns energy to the inverter. In this mode, the motor is braked via the inverter. For reliable braking, an external braking chopper has also to be used, depending on the energy levels involved.

  • Page 35: Function Of The Fsina Reference Value Input

    2.4.2 Function of the FSINA reference value input Setting FSINA analog frequency reference value The rotating field frequency is set at the terminals X1/2 and 7. Using jumper strip X2, the input is matched to the appropriate drive type. There are three possibilities for doing this: 1.
  • Page 36 Function table Apart from matching the FSIN input using jumper strip X2, the device software provides matching opportunities using the K or the interface. Parameter 04-FSSEL (frequency reference value selector) determines the origin of the frequency reference value and, with the details as set previously , must be 04-FSSEL = 4 (factory setting).

  • Page 37: Control Functions Using Str/Stl

    2.4.3 Control functions using STR/STL Warning: For safety reasons, the inverter must not be switched on to the mains supply using the preset control function STL or STR. The inverter only recognizes the start function if it has been activated after power on or self test.

  • Page 38: Control Function Using S1Ind/S2Ind

    2.4.4 Control function using S1IND/S2IND Choice of fixed frequencies FF2, FF3, FF4 In addition to the FSINA input, the frequency reference value can also be preset using control inputs S1IND/S2IND as a fixed frequency. There is a choice of three fixed frequencies which can be activated in accordance with the truth table.
  • Page 39 Data record switching The inverter has two data records which can be switched using the control inputs S1IND/S2IND. Each data record has a total of eight parameters which may be set individually (for further information, see "Descirption of parameters". The following truth table relates to parameter 31-KSEL = 2 (data record selector).
