Goodrive350 series VFD Auto Station programmable expansion card Safety precautions
i
Safety precautions
The expansion card must be installed and operated only by professionals who have taken part
in professional training on electrical operation and safety knowledge, obtained the certification,
and been familiar with all steps and requirements for the installing, commissioning, operating,
and maintaining, and are capable of preventing all kinds of emergencies.
Before installing, removing, or operating the expansion card, read the safety precautions
described in this manual and the variable-frequency drive (VFD) operation manual carefully to
ensure safe operation.
We are not responsible or liable for any physical injuries or device damage caused due to your
neglect of the safety precautions described in this manual and the VFD operation manual.
You need to open the VFD housing to install or remove the expansion card. Therefore,
you must disconnect all power supplies of the VFD and ensure that the voltage inside
the VFD is safe. For details, see the description in the VFD operation manual. Severe
physical injuries or even death may be caused if you do not follow the instructions.
Store the expansion card in a place that is dustproof and damp-proof without electric
shocks or mechanical pressure.
The expansion card is electrostatic sensitive. Take measurements to prevent
electrostatic discharge when performing operations involving it.
Tighten the screws up when installing the expansion card. Ensure that it is firmly fixed
and properly grounded.

2 Product overview
2.1 Expansion card introduction
GD350 series VFD Auto Station programmable expansion card (hereinafter called PLC card)
works with the VFD to replace small-size PLC in certain application cases. We develop the
Auto Station to perform secondary program development on the PLC card, supporting three
programmable languages, including the instruction language (IL), ladder diagram (LD), and
sequential function chart (SFC). The PLC card has 16K step user program storage space and
8K words data storage space (D elements) for easy development. After completing programs
on the Auto Station, you can upload the programs through the mini-USB interface to the PLC
card for running. The PLC card transfers data to the VFD so as to control VFD running and
modify parameters. In addition, the PLC card provides the power-outage saving function,
which will save the values about 1K words of the M/S/D/C elements in case of power outage if
you have specified the saving range on the Auto Station. You can use the RS485 channel for
network communication. The standard Modbus protocol has been embedded into the PLC
card so that the master/slave switchover can be performed on the Auto Station. The PLC card
also provides the DP/CANopen/PN card with the PZD channel, through which data can be
transferred from the DP/CANopen/PN card to the PLC card for secondary programming or
from GD350 to the PLC card and then transferred to the DP/CANopen/PN card.
When the PLC card works with the VFD, all the external I/O terminals of the VFD can be
invoked by the PLC card, enriching the I/O points of the PLC card.

3 Secondary development platform
3.1 Auto Station introduction
We have developed the Auto Station as the secondary development platform of PLC cards.
You can download the latest Auto Station from https://www.invt.com/.
If you have successfully installed the Auto Station, double-click the Auto Station. The interface
is displayed, as shown in the following:
Figure 3.1 Auto Station interface
3.2 PLC program download interface
If you want to download programs to the PLC card through the Auto Station, you need to
install the driver, use the mini-USB cable to connect the PLC card to the PC. If the driver cannot
be installed automatically, visit http://www.wch-ic.com/downloads/CH341SER_EXE.html and
download the CH341SER.EXE file for USB-serial port driver of PLC card. If you cannot install
it, contact us to obtain the driver and drive installation guide.
After installing the driver, open the Auto Station. After creating a project, choose PLC
Communication > Connect, and choose Program Port Setting. Set related parameters.

3.3 How to edit programs on the Auto Station
1. After opening the Auto Station, choose File > New Project to create a project. Select IVC1L
as the PLC type since the PLC card uses the structure of the IVC1L programmable controller
developed by us. See the following figure.
Figure 3.3 Creating a project
You can also choose Tool > Options… to change the default editor (program editing
language), PLC type, and interface language. The new project is an IVC1L project by default.
See the following figure.
