Bit
Function
controller. (Section 4.3.5).
FLOATING POINT
ENABLED
Controls whether 32-bit numbers are floating point or integer. When
set to “1”, all 32-bit numbers are floating point numbers (IEEE single
precision standard). When set to “0”, all 32-bit numbers are integer
numbers with a scale given specified in the register list of this
document.
FDR ENABLED
Activates the flight data recorder option. When set to “1”, the master
controller and modules controllers periodically save certain information
to internal non-volatile memory for later diagnostics. (Section 4.3.6).
RESET ENERGY
METER
Causes the cumulative energy meter to restart at zero. When changed
from “0” to “1”, the energy meter accumulator is reset.
ANALOG
VOLTAGE
OVERRIDE
Only applicable in analog programming mode when unit is to be
operated in current and/or power mode only, use this bit to ignore
analog voltage programming input. When set to “1”, the analog voltage
programming input is ignored and the voltage setpoint is set to
maximum.
ANALOG
CURRENT
OVERRIDE
Only applicable in analog programming mode when unit is to be
operated in current and/or power mode only, use this bit to ignore
analog current programming input. When set to “1”, the analog current
programming input is ignored and the current setpoint is set to
maximum.
ANALOG POWER
OVERRIDE
Only applicable in analog programming mode when unit is to be
operated in current and/or voltage mode only, use this bit to ignore
analog power programming input. When set t
o “1”, the analog power
programming input is ignored and the power setpoint is set to
maximum.
DIGITAL
PROGRAMMING
MODE
Tells the unit to receive setpoints from the digital interface or from the
analog interface. When set to “1”, the unit will receive setpoints from
the digital interface (digital programming mode*). If set to “0”, the
setpoints are taken from analog interface (analog programming mode).
*In digital programming mode, the output enable signal at the analog
interface must be set to high in order for the unit to turn on without a
fault.
PROCESS
CONTROL MODE
Controls an external process. When set to “1”, the unit is set to control
an external process, using the power programming analog input as the
feedback. (Section 4.3.8).
DISABLE
ANALOG
SATURATION
Only applicable in analog programming mode, when set to “1” and any
of the 3 ANALOG OVERRIDE bits is used, the setpoint used for that
variable is not saturated to maximum; but is taken from the digital
interface setpoint (e.g. register).
