Chapter 2 Installing the Adapter
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.
After installing the adapter and applying power, you can set the IP address by
using a BOOTP/DHCP server or adapter parameters. See
Setting the IP
Address, Subnet Mask, and Gateway Address on page 32 for details.
By default, the adapter is configured so that you must set the IP address using a
BOOTP/DHCP server or by setting the adapter to a valid address, 1-254, via the
rotary switches on the adapter. An invalid address 0 or >254 will cause the
module to defer to the addressing mode selected by parameter 3 [BOOTP/
DHCP]. If disabled, the adapter will use the address information stored in the
adapters database. If that address is invalid, the adapter will try to contact a
DHCP server on the network. To use adapter parameters, you must disable the
BOOTP feature. For details, see
Disable the BOOTP Feature on page 32 .
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.
