Frequency Inverter ST600 Series High-Performance Multifunction VFD Expansion cards
-308-
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.
Follow the following operation principles when installing or removing an expansion card:
1. Ensure that no power is applied before installing the expansion card.
2. The expansion card can be installed in any one of the SLOT1, SLOT2, and SLOT3 card slots.
3. The product can be configured with three expansion cards.
4. 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.
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.
