A.2 Dimensions and installation
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:
Ensure that no power is applied before installing the expansion card.
The expansion card can be installed in any one of the SLOT1, SLOT2, and SLOT3 card slots.
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.
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.
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.
