Fieldbus control through a fieldbus adapter 473
The start sequence for the parameter example above is given below.
Control word:
• 47Eh (1150 decimal) –> READY TO SWITCH ON
• 47Fh (1151 decimal) –> OPERATING (Speed mode)
Parameter setting example: Using PCP/ESP application through
FPBA
This example shows how to configure a PCP/ESP application for Profibus
communication using ABB Drives profile with PPO Type 8 telegram type. The
start/stop commands are according to the Main control word (
). Reference is according to application reference (
Example:
Assume that pump maximum speed is 80 Prpm and required speed is 60
Prpm. For ABB Drive profile fieldbus speed reference value 20000 corresponds to
maximum motor speed. For gear reduction ratio value 10 (
maximum pump speed 80 Prpm corresponds to fieldbus reference value 2000.
Fieldbus reference for 60 Prpm can be calculated as: 60 * 2000/ 80 = 1500.
Speed ref 1 in PZD 2 OUT should be equal to 1500.
If actual value 1 in PZD 2 IN equals 50, then pump speed is 50 Prpm.
The table below gives the recommended drive parameter settings.
