This parameter is applicable only if an optional DeviceNet Drive Profile
communication kit were used.
It allows programming the I/O instances used by the DeviceNet Drive
Profile interface. These instances define the contents and the number
of I/O words exchanged with the network master.
The modification of this parameter will become valid only after cycling
the power of the inverter.
In order to get more information on the parameterization and the operation
of the DeviceNet Drive Profile interface, refer to the CFW-09 frequency
inverter DeviceNet Drive Profile Communication Manual.
These parameters are applicable only if an optional DeviceNet Drive
Profile communication kit were used.
The parameters P336 to P340 permit programming the content of the
input words 3 to 7 (input: the inverter sends to the master). Using these
parameters it is possible to program the number of another parameter
whose content must be made available at the network master input
area.
If for instance one wants to read from the CFW-09 inverter the motor
current in Amps, one must program the value 3 in one of these
parameters, because the parameter P003 is the one that contains this
information. It is worthwhile to remind that the value read from any
parameter is represented with a 16 bit word with sign, in two’s
complement. Even if the parameter has decimal resolution, the value is
transmitted without the indication of the decimal point. E.g., if the
parameter P003 has the value 4.7 A, the value supplied via the network
will be 47.
These parameters are used only if the number of input/output words
programmed in P346 were greater than 2, and if the I/O instances 102/
103 were programmed in P335.
In order to get more information on the parameterization and the operation
of the DeviceNet Drive Profile interface, refer to the CFW-09 frequency
inverter DeviceNet Drive Profile Communication Manual.
