Goodrive350 series high-performance multifunction VFD
3. The 5.5 kW and lower VFD models can be configured with two extension cards at the same time,
and the 7.5 kW and higher VFD models can be configured with three extension cards.
4. If interference occurs on the external wires after extension cards are installed, change their
installation card slots flexibly to facilitate the wiring. For example, the connector of the connection
cable of the DP card is large, so it is recommended to be installed in the SLOT1 card slot.
5. To ensure high anti-interference capability in closed-loop control, you need to use a shielding wire
in the encoder cable and ground the two ends of the shielding wire, that is, connect the shielding
layer to the housing of the motor on the motor side, and connect the shielding layer to the PE
terminal on the PG card side.
The following shows the installation diagrams for different VFD models with extension cards installed.
