Sorensen SLD-Series DC Load Remote Programming
M540075-01 Rev C 5-11
This command is to set the lower limit value of threshold current. When load sink current is lower
than this lower limit value or higher than the upper limit value, NG indicating light will come on to
indicate “NO GOOD."
Example:
LIM:CURR:LOW:0.05 ; To set the lower limit value of threshold current to 0.05A.
LIM:CURR:HIGH:10.0 ; To the upper limit value of threshold current to 10.0A.
POWER Limit
Purpose:
To set the upper/lower limit value of threshold power (W).
Command Syntax:
LIM:POW:{HIGH|LOW}{SP}{NR2}{;|NL}
Description:
This command is to set the upper/lower limit value of threshold power (WATT). When power (WATT)
is lower than this lower limit value or higher than the upper limit value, NG indicating light will come
on to indicate “NO GOOD."
Example:
LIM:POW:LOW 0.05 ; To set the lower limit value of threshold power (W) to 0.05 W.
LIM:POW:HIGH 250.0 ; To set the upper limit value of threshold power(W) to 250.0 W.
PERIOD
Purpose:
Set the Tlow/Thigh duration of dynamic load in Constant Current mode.
Command Syntax:
PERI:{LOW|HIGH}{SP}{NR2}{NL}
Description:
The PERiod of dynamic waveform is composed by Tlow and Thigh. The PERIOD LOW and HIGH
data must include decimal point, otherwise this command will not execute.
The value for PERIOD LOW and HIGH can be programmed up to the sixth place after the decimal
point. If the period of Tlow and Thigh setting is over the maximum specification at programmed
range of load module, the maximum duration of Tlow and Thigh will be sent to the load module.
Please verify the appropriate timer range before executing the load PERI LOW or HIGH command,
otherwise the PERI load module will adjust to fit the Tlow and Thigh ranges after programming the
PERI LOW or HIGH command. The engineering unit for PERI LOW and HIGH is “ms."
Note:
1. There are four timer ranges in the Tlow / T high generator to produce a wide period
dynamic range, these ranges are adjusted by the load module automatically which
depends on the programmed Tlow / Thigh range.
Example:
PERI:LOW 0.125;PERI:HIGH 0.8
Set the LOW dynamic load duration to 0.125 ms, and the HIGH dynamic load duration to 0.8 ms.
