Fieldbus control through a fieldbus adapter 483

Parameter setting example: FPBA (PROFIBUS)
This example shows how to configure a basic speed control application that uses the
PROFIdrive communication profile with PPO Type 2. The start/stop commands and
reference are according to the PROFIdrive profile, speed control mode.
The reference values sent over the fieldbus have to be scaled within the drive so they
have the desired effect. The reference value ±16384 (4000h) corresponds to the
range of speed set in parameter
46.01 Speed scaling (both forward and reverse
directions). For example, if 46.01 is set to 480 rpm, then 4000h sent over fieldbus will
request 480 rpm.
The table below gives the recommended drive parameter settings.
