Programming Manual Lx \ Ls Series II

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:
MOD PHS 3
