Configure the Interface Chapter 2
Configuring and Verifying Key Drive Parameters
The PowerFlex 755T drive can be separately configured for the command logic
and reference functions in various combinations. For example, you could set
the drive to have the logic command come from a peripheral or terminal block
but have the reference come from the network. Or you could set the drive to
have its control come from the network with the reference that comes from
another peripheral or terminal block. Or you could set the drive to have both
its logic command and reference come from the network.
The following steps in this section assume that the drive receives the logic
command and reference from the network.
1. To access the required parameters in this procedure, verify that drive
parameter 0:30 - [Access Level] is set to ‘1’ (Advanced) or ‘2’ (Expert).
2. To set the drive velocity reference, use drive 10:1800 - [VRef A Sel].
a. Set the Port field to ‘10 - Pri MtrSideCtrl’ as shown.
b. Set the Parameter field to point to Port 0, which contains the
EtherNet/IP interface.
c. Then choose Parameter 211 [Emb Enet Ref ].
3. Verify that drive 10:350 - [VRef Source] matches your entry to
10:1800 [VRef A Sel].
Any velocity reference that is commanded from the network can be
monitored by using 0:1914 - [VRef Command]. If a problem occurs,
this verification step provides the diagnostic capability to determine
whether the drive, interface, or the network is the cause.
4. If hard-wired discrete digital inputs are not used to control the drive,
verify that all unused digital input drive parameters are set to ‘0’ (Not
Used). These parameters are located in Port 0, in the file Feedback & I/
O, group Command.
Use Interface Parameters to
Set the IP Address
By default, the interface is configured to use a DHCP server as the source for
the IP address interface, subnet mask, and gateway address. To use interface
parameters instead, you must first change the source for the node address to
Parameters by using 0:300 - [Net Addr Sel]. Set the associated interface
parameters as described in the following subsections.
