Fieldbus control through a fieldbus adapter 543 Parameter setting example: FPBA (PROFIBUS DP)This example shows how to configure a basic speed control application that uses thePROFIdrive communication profile with PPO Type 2. The start/stop commands andreference are according to the PROFIdrive profile, speed control mode.The reference values sent over the fieldbus have to be scaled within the drive so theyhave the desired effect. The reference value ±16384 (4000h) corresponds to therange of speed set in parameter 46.01 Speed scaling (both forward and reversedirections). For example, if 46.01 is set to 480 rpm, then 4000h sent over fieldbus willrequest 480 rpm.The table below gives the recommended drive parameter settings.Direction PZD1 PZD2 PZD3 PZD4 PZD5 PZD6Out Control word Speed reference Acc time 1 Dec time 1In Status word Speed actual value Motor current DC voltageDrive parameter Setting for ACS880drivesDescription50.01 FBA A enable 1…3 = [slot number] Enables communication between thedrive and the fieldbus adapter module.50.04 FBA A ref1 type 4 = Speed Selects the fieldbus A reference 1 typeand scaling.50.07 FBA A actual 1 type 0 = Auto Selects the actual value type/source andscaling according to the currently activecontrol mode (as displayed by parameter19.01).51.01 FBA A type 1 = FPBA1) Displays the type of the fieldbus adaptermodule.51.02 Node address 3 2) Defines the PROFIBUS node address ofthe fieldbus adapter module.51.03 Baud rate 12000 1) Displays the current baud rate on thePROFIBUS network in kbit/s.51.04 MSG type 1 = PPO11) Displays the telegram type selected bythe PLC configuration tool.51.05 Profile 0 = PROFIdrive Selects the Control word according to thePROFIdrive profile (speed control mode).51.07 RPBA mode 0 = Disabled Disables the RPBA emulation mode.52.01 FBA data in1 4 = SW 16bit1) Status word52.02 FBA data in2 5 = Act1 16bit Actual value 152.03 FBA data in3 01.07 2) Motor current52.05 FBA data in5 01.11 2) DC voltage53.01 FBA data out1 1 = CW 16bit1) Control word53.02 FBA data out2 2 = Ref1 16bit Reference 1 (speed)
