To program Drop Cycles (DRP)

The DRP header is used to identify the Drop Command. The argument is a numeric data field from
1 to 5. The following string will drop the output voltage for phase B for five complete cycles and start
at 0 degree of the waveform. Note that all drop phase angles are relative to Phase A.

PHZ A 120 DRP B

To program the Default Frequency (FLM A)

The default frequency is the output frequency after power-up or after an IEEE-488 Device Clear. The
following example will program the default frequency to 400 Hz.

FLM A 400

To program the default Voltage (INI A)

The default voltage is the output voltage after power-up, IEEE-488 Device Clear or an Amplitude
fault. The following example will program the default voltage to 5 volts.

INI A 5

NOTE: The restrictions on setting initial voltage that applied to the L Series do not apply to the Ls
Series so any voltage amplitude - within the selected voltage range - can be set at initialization.

To program the default Current Limit (INI C)

The default current limit is the value after power-up or IEEE-488 Device Clear. The following
example will program the default current limit to 10 amps.

INI C 10

To program the default Voltage Range (ALM A)

The default voltage range is the voltage range after power-up or IEEE-488 Device Clear. A value of
0 designates the low-range. A value of 8 designates the high range. The following example will
program the default voltage range to the high range.

ALM A 8

To program 1 or 3 Phase Mode (MOD) (optional)

This command is valid only for Ls Series models with the

–3 controller and the –MODE option. The

MOD header with the required PHS extension is used to identify the mode command. The argument
is either a 1 or a 3 to specify the 1-phase or 3-phase mode respectively. A mode change by the AC
Power System will cause the output voltage to go to the default values. The following string will set
the AC Power Systems to the 3-phase mode:
