All expansion cards are of the same dimensions (108 mm × 39 mm) and can be installed in the same way.
Following the operation principles when installing or removing an expansion card:
l Ensure that no power is applied before installing the expansion card.
l The expansion card can be installed in any one of the SLOT1, SLOT2, and SLOT3 card slots.
l The VFD models of 5R5G/7R5P and lower can be configured with two expansion cards at the same time, and those of 7R5G/011P and higher can be configured with three expansion cards.
l If interference occurs on the external wires after expansion 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.
l 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 figure shows the installation diagram and the VFD with expansion cards installed.
