Default Value:
This configuration is the default for PowerFlex 70/700 drives. For other
drives, the defaults are 0 and need to be configured prior to network
commissioning. A value of 0 means the variable is disabled and cannot be
used to send/receive data.
Note: It is necessary to configure nciNmlFreq and nciMaxSpeed to operate
the drive from the network.
Variable: nviDatalinkA1
nviDatalinkA2
nviDatalinkB1
nviDatalinkB2
nviDatalinkC1
nviDatalinkC2
nviDatalinkD1
nviDatalinkD2
Format: UNVT_DATALINK
Explanation:
These network variable inputs are used for generic parameter writes by way
of Datalink Ins. To set up a Datalink, configure the adapter according to the
drive manual. All data is sent in raw format; that is, no scaling is performed.
Example:
If PowerFlex 70/700 drive parameter 300 - [Data In A1] is set to ‘101’, it is
pointing to drive parameter 101 - [Preset Speed 1]. Any value written to
nviDatalinkA1 updates drive parameter 101 - [Preset Speed 1] with the
value. A value of ‘100’ equates to 10.0 Hz (note that no scaling is
performed).
