GD350A Accessories
● 1 PT100
● 1 PT1000
● 2 relay outputs: single-contact NO outputs
Note: The expansion card has been built into the 7.5kW and higher VFD models but it is optional for the VFD models of lower than 7.5kW. For details, see section 4.4.3 Control circut wiring of I/O expansion card
Additional notes:
On page 8: P16.32 and following for PZD mapping
On page 40: P15.43=1 switches to bitwise communication (only FU firmware 3.02.XX)
The FU firmware 1.01 and 1.05 can only communicate byte-wise.
Profinet IP addresses in FU firmware 1.0X on P16.02 to P16.05
Profinet IP addresses in FU firmware 3.02 on P16.58 to P16.61
In the documentation attached you will also find a parameter example, as well as Profinet simulator example commands.
• Applies to 24V-OC-Geber
• Applies to 24V-Push-Pull-Geber
• Applies to 5V-Differenzialgeber
• Supports orthogonal input A, B, Z
Supports frequency-divided output A, B, Z
Supports the input of the pulse sequence setpoint value
The expansion card can be installed in one of the card slots SLOT1, SLOT2 and SLOT3. The VFD models 5R5G/7R5P and below can be configured with two expansion cards at the same time, the models 7R5G/011P and higher can be configured with three expansion cards.
To ensure high interference resistance during the control, you must use a shielding wire in the transmitter cable and ground the two ends of the shielding wire, i.e. h connect the shielding layer on the motor side to the motor housing and on the PG card side to the PE terminal.
Industrial USB TO RS485 Bidirectional Converter, Onboard original CH343G, Multi-Protection Circuits
CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.
Features at a Glance
1. Support USB to RS485 bidirectional conversion.
2. Onboard original CH343G chip, CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.
3. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.
4. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
5. 3 LEDs for indicating the power and transceiver status.
6. Supports Mac, Linux, Android, WinCE, Win11/10/8.1/8/7/XP, etc.
6. Fast communication, stable and reliable, better compatibility.
