PowerFlex 520-Series Adjustable Frequency AC Drive
The following PowerFlex 520-series drive parameters are used to configure the drive to operate on a DSI network.
PowerFlex 525 Embedded EtherNet/IP
This section contains only basic information to setup an EtherNet/IP connection with your PowerFlex 525 drive. For
comprehensive information about EtherNet/IP (single and dual-port) and how to use it, see the following publications:
• PowerFlex 525 Embedded EtherNet/IP Adapter User Manual, publication 520COM-UM001
.
• PowerFlex 25-COMM-E2P Dual-Port EtherNet/IP Adapter User Manual, publication 520COM-UM003
.
Connecting the Adapter to the Network
1. Remove power from the drive.
2. Remove the drive control module cover.
3. Use static control precautions.
4. Connect one end of an Ethernet cable to the EtherNet/IP network.
5. Route the other end of the Ethernet cable through the bottom of the PowerFlex 525 drive, and insert the cable’s plug
into the embedded EtherNet/IP adapter’s mating socket.
Configuring Parameters for DSI Network
Parameter Description
P046 [Start Source 1] Set to 3 “Serial/DSI” if Start is controlled from the network
P047 [Speed Reference1] Set to 3 “Serial/DSI” if Speed Reference is controlled from the network.
C123 [RS485 Data Rate] Sets the data rate for the RS485 (DSI) port. All nodes on the network must be set to the same data rate.
C124 [RS485 Node Addr] Sets the node address for the drive on the network. Each device on the network requires a unique node address.
C125 [Comm Loss Action] Selects the drive’s response to communication problems.
C126 [Comm Loss Time] Sets the time that the drive will remain in communication loss before the drive implements C125 [Comm Loss Action].
C127 [Comm Format] Sets the transmission mode, data bits, parity, and stop bits for the RS485 (DSI) port. All nodes on the network must be set to the same setting.
C128 [Comm Write Mode] Set to 0 “Save” when programming drive.
Set to 1 “RAM only” to only write to volatile memory.
ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove
power from the drive, and then verify power has been discharged before connecting the embedded EtherNet/IP adapter to the
network.
