2.1.6. OUT Command

The OUT command can be used to enable/disable the power supply output and to monitor the status of the power supply. The power supply output state is not controlled only by the OUT command, but its state depends on the related Finite State Machine (see Power Supply Finite State Machine). For this reason the OUT command do not control directly the power supplies output, but it evolves the related FSM, that controls the power supply output.

Command Format:

R/W	Command	Response	Notes
R	OUT:?	#OUT:<state>	<state> can be ON|OFF|W4OFF
W	OUT:<state>	#AK / #NAK	<state> can be ON|OFF

Parameter(s):

<state>	Mode	Description
ON	R	FSM is in ON state, power stage is enabled and the PID controller is running, following the selected setpoint
	W	Makes it evolve the FSM is in ON state
OFF	R	FSM is in OFF state, power stage is disabled and the PID controller is in reset
	W	Makes it evolve the FSM is in Wait for OFF state, when the FSM is in ON state; and makes it evolve the FSM is in OFF state, when the FSM is in Wait for OFF state
WAIT4OFF	R	FSM is in Wait For OFF state, power stage is enabled and the PID controller is running, the module performs a fast ramp to zero. The module remains in this state until the output current is about 0A and then the FSM evolves automatically in OFF state.

Example(s):

OUT:?
#OUT:OFF

OUT:ON
#AK

OUT:?
#OUT:ON
