Step 3: Set AC Drive Parameters
The following parameters need to be set as shown in order to communicate
properly.
P3.00: 03 or 04 Operation Determined by RS-485 interface.
Keypad STOP is enabled (03) or disabled (04).
P4.00: 05 Frequency determined by RS-485 communication
interface.
P9.00: xx Communication address 1-254
(unique for each device, see P9.00).
P9.01: 01 9600 baud data transmission speed
(higher baud rate setting may be required with
FA-ISOCON network adapter; set adapter DIP switches
accordingly).
P9.02: 05 MODBUS RTU mode
<8 data bits, odd parity, 1 stop bit>.
Step 4: Configure the PLC CPU
The PLC CPUs must be configured to communicate with the DURAPULSE AC
drives. This configuration includes setting up the communication port and adding
instructions to your logic program.
The set up for all of the AutomationDirect PLC CPUs is very similar, although
there are some subtle differences between CPUs. Refer to the appropriate CPU
User Manual for the specifics on your specific PLC CPU if more details are
needed.
Configure the CLICK PLC
Configure the CLICK CPU communication port before writing communication
instructions into your logic program.
For more detailed instructions on Modbus Configuration for your CLICK, refer to the
CLICK PLC Hardware User Manual, C0-USER-M, or to the CLICK software help file.
For instructions on Modbus Configuration for your specific PLC CPU, refer to the
appropriate PLC User Manual.
This list of parameter settings is the minimum required to communicate with a
DirectLOGIC PLC. There may be other parameters that need to be set to meet the
needs of your particular application.
