Fieldbus equivalent

Serial communication data between fieldbus adapter and drive is transferred in
integer format. Thus the drive actual and reference signal values must be scaled to
16/32-bit integer values. Fieldbus equivalent defines the scaling between the signal
value and the integer used in serial communication.
All the read and sent values are limited to 16/32 bits.
Example: If 32.04 MAXIMUM TORQ REF is set from external control system,
an integer value of 10 corresponds to 1%.

Fieldbus addresses

For FPBA-01 Profibus Adapter, FDNA-01 DeviceNet Adapter and FCAN-01
CANopen Adapter, see the User's Manual of the fieldbus adapter module.

Pointer parameter format in fieldbus communication

Value and bit pointer parameters are transferred between the fieldbus adapter and
drive as 32-bit integer values.

32-bit integer value pointers

When value pointer parameter is connected to the value of another parameter or
signal, the format is as follows:
Name
Value
Description
When value pointer parameter is connected to an application program, the format is
as follows:
Name
Value
Description
Note: Value pointer parameters which are connected to an application program
cannot be set via fieldbus (i.e. read access only).
