7.38 MODBUS FIELDBUS (STANDARD EXPANSION CARD
CONFIGURATION) (GROUP FA.0)
FA.0.02 The inverter station address
Setting range: 0~247
Factory default: 1
This parameter is used to set the address of the local inverter in the case of serial port communication. It is
only effective when the inverter is a slave one. During communication, the local device only receives
commands for the data frames consistent with the address of this device, and then sends back response
frames.
FA.0.03 The device response delay
Setting range: 0~1000ms
Factory default: 5ms
The response delay of the inverter refers to the waiting time since the inverter serial port has received and
explained the command sent from the slave device till the response frames are sent.
FA.0.04 Communication failure
judging time
Setting range:
0.01~10.00Sec.
Factory default: 1.00
If the local inverter has not received correct data signal beyond the time interval defined by this parameter,
then the communication is judged to be failed for the local inverter. The inverter will report
Fu.071
fault, and
will act as set by
FA.0.05.
7.39 MAPPING PARAMETER ACCESS (GROUP FA.1)
FA.1.08~FA.1.13 Mapping application
parameter 1~6 (H)
Setting range: F0.00~FF.55
Factory default:
F0.29/F0.32
FA.1.14~FA.1.23 Mapping status
parameter 1~10 (H)
Setting range: d0.00~d1.49
Factory default:
d0.00~d0.09
When
V260
series inverter makes access to functional parameters or monitoring parameters via the buss,
corresponding address can be predicted directly with the functional code. However, when it is needed to
access multiple functional parameters or monitoring parameters with discontinuous address, multiple-frame
data are needed in this method.
The mapping parameter access is actually a needle access mode. When accessing
(reading or writing)
several functional parameters or status parameters with discontinuous address, these parameters can be
mapped into an area with continuous address (bus-control parameter area) for accessing.
See the following table for the bus-control parameters (compatible with A510).

0 is the broadcasting address. When it is set to the broadcasting address, the device will
only receive and execute broadcasting commands and will not respond to the master
device.
