2.9.3: CAN Interface Status Indicator Operation
The amplifier status indicator color/blink codes comply with CAN Indicator Specification 303-3 as
described below. Note that green and red codes are often interlaced, each indicating a different
set of conditions. The green codes indicate the CANopen state machine mode of operation (pre-
operational, operational, or stopped). The red codes indicate the status of the physical bus
(warning or error conditions).

In addition, the CAN status indicator is turned off when the CAN node ID selector (CAN ADDR) is
set to 0. A setting of 0, which is invalid, shuts down most operations on the CAN interface, and the
light is shut off to indicate this status.
