Configuring and Verifying Key Drive Parameters
The PowerFlex 7-Class drive can be separately configured for the control
and Reference functions in various combinations. For example, you could
set the drive to have its control come from a peripheral or terminal block
with the Reference coming from the network. Or you could set the drive to
have its control come from the network with the Reference coming from
another peripheral or terminal block. Or you could set the drive to have both
its control and Reference come from the network.
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed
Reference to ‘22’ (DPI Port 5).
2. If hard-wired discrete digital inputs are not used to control the drive,
verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and
362 - [Dig In2 Sel] are set to ‘0’ (Not Used).
3. Verify that drive Parameter 213 - [Speed Ref Source] is reporting that
the source of the Reference to the drive is ‘22’ (DPI Port 5).
This ensures that any Reference commanded from the network can be
monitored by using drive Parameter 002 - [Commanded Speed]. If a
problem occurs, this verification step provides the diagnostic capability
to determine whether the drive/adapter or the network is the cause.
Commissioning the Adapter
To commission the adapter, you must set a unique IP address on the
network. See the
Glossary for details about IP addresses. After installing the
adapter and applying power, you can set the IP address by using a BOOTP
server or adapter parameters. See
Using Parameters to Set the IP Address,
Subnet Mask, and Gateway Address on page 3-5 for details.
By default, the adapter is configured so that you must set the IP address
using a BOOTP server. To use adapter parameters, you must disable the
BOOTP feature. For details, see
Disable the BOOTP Feature on page 3-5 .
Important: New settings for some adapter parameters (for example,
Parameters 04 - [IP Addr Cfg 1] through 07 - [IP Addr Cfg
4]) are recognized only when power is applied to the adapter or
it is reset. After you change parameter settings, cycle power or
reset the adapter.
TIP: For PowerFlex 750-Series drives, use drive Parameter 545 -
[Speed Ref A Sel] to set the drive speed Reference:
a. Set the Port field to ‘0 - PowerFlex 75x’.
b. Set the Parameter field to point to the port (slot) in which the
20-COMM-E adapter/20-750-20COMM Communication Carrier
Card are installed (for this example, ‘876 - Port 6 Reference’).
The number ‘876’ in the Parameter field of the example is the
parameter in the drive that points to the port.
