A.6.1 Bluetooth communication card
EC-TX501 and WIFI communication card––EC- TX502
Definitions of indicators and function buttons:
Indicator No. | Definition | Function |
LED1/LED3 | Bluetooth/WIFI state indicator | LED is on when the extension card is establishing a connection with the control board; LED blinks periodically after the extension card is properly connected to the control board (the period is 1s, on for 0.5s, and off for the other 0.5s); and LED is off when the extension card is disconnected from the control board. |
LED2 | Bluetooth communication state indicator | This indicator is on when Bluetooth communication is online and data exchange can be performed. It is off when Bluetooth communication is not in the online state. |
LED5 | Power indicator | This indicator is on after the control board feeds power to the Bluetooth card. |
SW1 | WIFI factory reset button | It is restored to default values and returned to the local monitoring mode. |
SW2 | WIFI hardware reset button | It is used to reboot the extension card. |
The wireless communication card is especially useful for scenarios where you cannot directly use the keypad to operate the VFD due to the restriction of the installation space. With a mobile phone APP, you can operate the VFD in a maximum distance of 30 m. You can choose a PCB antenna or an external sucker antenna. If the VFD is located in an open space and is a molded case machine, you can use a built-in PCB antenna; and if it is a sheetmetal machine and located in a metal cabinet, you need to use an external sucker antenna.
When installing a sucker antenna, install a wireless communication card on the VFD first, and then lead the SMA connector of the sucker antenna into the VFD and screw it to CN2, as shown in the following figure. Place the antenna base on the chassis and expose the upper part. Try to keep it unblocked.

A.6.2 PROFIBUS-DP communication card
EC-TX503
CN1 is a 9-pin D-type connector, as shown in the following figure.
Connector pin | Description | |
1 | - | Unused |
2 | - | Unused |
3 | B-Line | Data+ (twisted pair 1) |
4 | RTS | Request sending |
5 | GND_BUS | Isolation ground |
6 | +5V BUS | Isolated power supply of 5 V DC |
7 | - | Unused |
8 | A-Line | Data- (twisted pair 2) |
9 | - | Unused |
Housing | SHLD | PROFIBUS cable shielding line |
+5V and GND_BUS are bus terminators. Some devices, such as the optical transceiver (RS485), may need to obtain power through these pins.
On some devices, the transmission and receiving directions are determined by RTS. In normal applications, only A-Line, B-Line, and the shield layer need to be used.
Indicator definition
Indicator No. | Definition | Function |
LED1 | State indicator | This indicator is on when the extension card is establishing a connection with the control board; it blinks periodically after the extension card is properly connected to the control board (the period is 1s, on for 0.5s, and off for the other 0.5s); and it is off when the extension card is disconnected from the control board. |
LED2 | Online indicator | This indicator is on when the communication card is online and data exchange can be performed. It is off when the communication card is not in the online state. |
LED3 | Offline/Fault indicator | This indicator is on when the communication card is offline and data exchange cannot be performed. It blinks when the communication card is not in the offline state. It blinks at the frequency of 1 Hz when a configuration error occurs: The length of the user parameter data set during the initialization of the communication card is different from that during the network configuration. It blinks at the frequency of 2 Hz when user parameter data is incorrect: The length or content of the user parameter data set during the initialization of the communication card is different from that during the network configuration. It blinks at the frequency of 4 Hz when an error occurs in the ASIC initialization of PROFIBUS communication. It is off when the diagnosis function is disabled. |
LED4 | Power indicator | This indicator is on after the control board feeds power to the communication card. |
For details about the operation, see the Goodrive350 Series VFD Communication Extension Card Operation Manual.
