Xantrex Technology GPIB-XPD manual Operation, Command, Description

Operation

Command Reference

Command	Description
FOLD?	Asks for the supply’s present foldback setting.
	Response: FOLD <mode> where mode is:
	0 (OFF) or
	1 (CV or Constant Voltage mode) or
	2 (CC or Constant Current mode)
HOLD <1/ON>,<0/OFF>	Enables or disables voltage/current setting hold mode for the supply. When
	HOLD ON is specified, hold mode is enabled so that all voltage and current
	settings which would normally be implemented by the supply are held until a
	TRG (trigger) command is received. This feature allows you to synchronize
	the operation of several supplies.
	Initial value: HOLD OFF or HOLD 0
HOLD?	Asks for the present hold mode setting.
	Response: HOLD 0 (OFF or disabled) or
	HOLD 1 (ON or enabled)
ID?	Asks for the power supply model and the master EPROM version.
	Response: ID <model name><version>
IDATA <Ilo>,<Ihi>	Calculates and records the slope and offset for programmed current using
	ILO and IHI data. Set CMODE ON before using this command. See also the
	calibration procedures in Section 4.
	<Ilo> and <Ihi> are in <current> format.
IHI	In response to this command, the power supply sends a programmed
	current value to the output terminal. This value is at the high end of the
	power supply’s current range and is read by an external device connected
	as part of the calibration procedure. Refer to this value as IHI and record it
	to use as input with the IDATA command. Set CMODE ON before using this
	command. See also the calibration procedures in Section 4.
ILO	In response to this command, the power supply sends a programmed
	current value to the output terminal. This value is at the low end of the
	power supply’s current range and is read by an external device connected
	as part of the calibration procedure. Refer to this value as ILO and record it
	to use as input with the IDATA command. Set CMODE ON before using this
	command. See also the calibration procedures in Section 4.
IMAX <current>	Sets an upper soft limit on the supply’s programmed output current. If the
	soft limit is exceeded, or if the soft limit value is lower than the present
	output current setting, the supply will ignore the command, turn on the
	ERR LED, and set the ERR bit in the bit registers.
	Range: 0 to model maximum output current (IMAX)
	Initial value: model IMAX
IMAX?	Asks for the supply’s soft current limit setting.
	Response: IMAX <current>
IOUT?	Measures the supply’s actual current output using the built-in current
	readback circuitry.
	Response: IOUT <current>
