Determining the parameter index in MOVISUITE®

In order to be able to access the drive parameters of the decentralized inverter with CTT2 services, the index and subindex of the parameter must be known. These can be determined in the MOVISUITE® engineering tool.

Proceed as follows:

  • A MOVISUITE® project with a decentralized inverter has been created.
  1. Launch the MOVISUITE® project and open the configuration of the inverter.
  2. Hover the cursor over a parameter.
    • The parameter properties are displayed.
    • In this example, the index and subindex of the Einschaltstunden parameter are determined.

Unique menu number in MOVISUITE®

Index

Index.Subindex offset, bit

Offset optional – If an offset is not displayed, the offset is 0.

Bit mask optional – If the parameter contains multiple values, the bit mask is applied to determine the desired value.

Data typeFor the BitField or range of values data types, individual bits or values can be defined in the firmware as "Reserved" or "Invalid". In the case of a write access with invalid values, the corresponding error is returned via the Response message. To prevent this, only the values displayed in the tooltip are allowed to be used.

The following data types are possible:

  • Int32 – Signed integer value, range of values: 32 bits
  • UInt32 – Unsigned integer, range of values: 32 bits
  • BitField – Different binary functions are assigned to each individual bit.
  • ParaBitPtr – Pointer to an internal firmware function

SI unit/user unit

Unit of the parameter

The user unit is a unit of measurement defined by the user (e.g. speed values).

Read access

Value: OBSERVER

Access to the available device functions that are visible in the parameter tree may be restricted by the parameter setting mode, parameter lock, drive states, energy saving mode, etc.

Read access is also possible in restricted inverter states.

Write access

The following values are possible:

  • NOBODY – Write access is not permitted.
  • OPERATOR – Access to the available device functions that are visible in the parameter tree may be restricted by the parameter setting mode, parameter lock, drive states, energy saving mode, etc. Write access is not permitted in restricted inverter states.
  • OBSERVER – Write access is also possible in restricted inverter states.
  • OEM-SERVICE – Write access is only possible with extended authorization. If necessary, contact SEW-EURODRIVE Service.

Value

  • "Device" column – Unscaled firmware value that is used for read access or write access to the parameter service. The scaling is displayed in brackets.For the BitField or range of values data types, individual bits or values can be defined in the firmware as "Reserved" or "Invalid". In the case of a write access with invalid values, the corresponding error is returned via the Response message. To prevent this, only the values displayed in the tooltip are allowed to be used.
  • "Display" column – Scaled display value. In the case of parameters with a range of values (enumeration), the set value is displayed here.

  1. Note the index and subindex of the parameter.
    • In this example, the parameter has the Index.Subindex: 8328.1
  2. Convert the decimal representation of the index and subindex to hexadecimal representation.
    • In this example, the hexadecimal representation of the Index.Subindex is: 0x2088.0x01
