Description
For the NX6100 and PPC6000, the NXDBVSD add-on card must be added to the system to enable the use of a VFD. To fit this card, the control must be powered down, the rear cover removed, the protective sticker removed from the side, and the card fitted into the bottom of the control in the header provided. The terminal blocks are part of the card and will be exposed for external connections. Once the rear cover is replaced, apply power, and the VFD can be wired to the connections on the terminal block, and the VFD channels can be configured for use.
The NXDBVSD offers interfaces for up to two VFDs with either encoder feedback or with 4-20mA feedback from the VFD. The analog inputs or outputs from any unused channels can be used as programmable analog inputs or user-assignable analog outputs. Using this card also enables the Modbus RTU connection for BMS use.
