Communication extension card
the fieldbus master station to a VFD device. In this case, the EC-TX-103 communication card
functions as a gateway. The VFD device responds to the bit code information of the CW and
feeds state information back to the master through an SW.
Reference value: A VFD device may receive control information in multiple channels, including
analog and digital input terminals, VFD control panel, and communication modules (such as
RS485 and EC-TX-103 communication cards). To enable the control over VFD devices
through PROFIBUS, you need to set the communication module as the controller of the VFD
device.
Actual value: An actual value is a 16-bit word that includes information about VFD device
operation. The monitoring function is defined through VFD parameters. The conversion scale
of an integer transmitted as an actual value from the VFD device to the master depends on the
set function. For more description, see the related VFD operation manual.
Note: A VFD device always checks the bytes of a CW and reference value.
Task packet (master station -> VFD)
CW: The first word in a PZD task packet is a VFD CW. Table 2-5 describes Goodrive350
series VFD CWs.
