Sorensen SLM-Series DC Load Remote Programming
M540071-01 Rev C 5-13
To set synchronous function ON/OFF of SLM AC series electronic load module.
Command Syntax:
SLM AC Modules:
SYNC{SP}{0|1|OFF|ON}{;|NL}
Description:
1. External synchronous signal (SYNC ON):Using external synchronous signal as the
synchronous triggering signal of the electronic load, synchronizing the load current with the
voltage.
2. Internal synchronous signal (SYNC OFF):Using the signal at the terminal of the input connector
thus generating synchronous signal through the internal zero-crossing circuit and isolated
circuit.
Example:
SYNC ON ; To set external synchronization.
SYNC OFF ; To set internal synchronization.
WATT Meter ON/OFF
Purpose:
To set display of power meter of SLM AC series electronic load module.
Command Syntax:
SLM AC Modules:
WATT{SP}{0|1|OFF|ON}{;|NL}
Description:
This command is to set the power meter display. This command must be used in conjunction with
PRES:OFF. When setting to ON, the top monitor will change from voltmeter to Watt meter while the
monitor at the bottom will change from ammeter to Volt-Ameter (VA) and the unit is “W＂ and “
VA＂ respectively. When setting to OFF, the Watt meter on the top will change back to voltmeter
while the VA meter at the bottom will change back to ammeter and the unit is “Vrms＂ and “
Arms＂ respectively.
Example:
PRES OFF
WATT ON ; to display WATT, VA meter.
WATT OFF ; to display Voltage, Current meter.
WAVEFORM BANK
Purpose:
To set waveform bank for AC electronic load modules.
Command Syntax:
SLM AC Modules:
BANK{SP}{d}{;|NL} d:0-10
Description:
This command is to set the desired waveform bank.
1. waveform bank 0-4 are sine wave.
2. waveform bank 5-9 are square wave.
3. waveform bank 10 is DC.
4. There are five (5) waveforms for each of eleven (11) waveform banks for a total of 55
waveforms. Waveform information is shown in Table 5-8.
