Xantrex Technology XHR, XFR, XFR3 manual Response Vmax voltage

	Operation
	Command Reference
Command	Description
VMAX <voltage>	Sets an upper soft limit on the supply’s programmed output voltage. If the
	soft limit is exceeded, or if the soft limit value is lower than the present
	output voltage setting, the supply will ignore the command, turn on the
	ERR LED, and set the ERR bit in the accumulated status register.
	Range: 0 to model maximum output voltage (VMAX)
	Initial value: model VMAX
VMAX?	Asks for the supply’s soft voltage limit setting.
	Response: VMAX <voltage>
VOUT?	Measures the supply’s actual voltage output using the built-in voltage
	readback circuitry.
	Response: VOUT <voltage>
VRDAT <Vlo>,<Vhi>	Calculates and records the slope and offset for readback voltage using
	VRLO and VRHI data. Set CMODE ON before using this command. See
	also the calibration procedures in Section 4 .
	<Vlo> and <Vhi> are in <voltage> format.
VRHI	The power supply outputs a voltage value to an external voltmeter
	connected as part of the calibration procedure and records a voltage
	readback value internally. These values are at the high end of the
	programmed voltage range. Refer to the output value as VRHI and record it
	to use as input with the VRDAT command. Set CMODE ON before using
	this command. See also the calibration procedures in Section 4.
VRLO	The power supply outputs a voltage value to an external voltmeter
	connected as part of the calibration procedure and records a voltage
	readback value internally. These values are at the low end of the
	programmed voltage range. Refer to the output value as VRLO and record it
	to use as input with the VRDAT command. Set CMODE ON before using
	this command. See also the calibration procedures in Section 4.
VSET <voltage>	Sets the power supply’s output voltage in volts (default) or in millivolts. This
or	programmed voltage is the actual output in CV (constant voltage) mode or
VSET <-voltage>	the voltage limit in CC (constant current) mode.
	If you enter a negative voltage value, the power supply will assert a signal
	on the J7-4 user signal line. You can use the user signal to trip external
	relays to switch the output polarity.
	Range: 0 to model maximum output voltage (VMAX)
	Initial value: 0 volts
VSET?	Asks for the power supply’s present output voltage setting. Does not apply
	to voltage settings which are being held. See HOLD command.
	Response: VSET <voltage>
