To transfer the parameter write value to active memory, set BV55 to ON.
To transfer the parameter write value to active and non-volatile memory, set BV56 to ON. Care must be taken when using
BV56. When non-volatile memory writes are exhausted, the control card will have to be replaced.

Corrective Action
Communication from BACnet Option to drive
fails.
If enabled (H5-05 = 1), a CE fault will stop the
motor as selected by H5-04.
• Check that the PWR LED is on.
• Check cable connections on drive terminal
assembly.
• Check connection on J2 on the BACnet
Option.
• Check that the termination resistor on the
terminal assembly is OFF.
• Check that parameters H5-01 through H5-09
are at their correct values.
Communication from drive to BACnet Option
fails.
The drive will declare an EF0 fault.
If enabled (F6-02 = 1), and EF0 will stop the
motor as selected by F6-03.
• Check that the PWR LED is on.
• Check cable connections on drive terminal
assembly.
• Check connection on J2 on the BACnet
Option.
• Check that parameters H5-01 through H5-09
are at their correct values.
Communication on BACnet fails.
The drive will declare an EF0 fault.
If enabled (F6-02 = 1), an EF0 will stop the
motor as selected by F6-03.
• Check that the PWR LED is on.
• Check BACnet cable connections.
• Check BACnet cable.
• Check the termination resistor on the
BACnet Option.
• Check that the BACnet controller and
associated routers are running and that the
BACnet network is active.
Note:
An EF0 may also be declared from the controller by setting either BV3 or AV1 bit 2 (AV1 bits are numbered from 0 to 15) to 1.
If an EF0 is set from the controller, it may be reset by a restoration of the network communications.
