4.2.2 Setting of reference value / protection threshold
T he display and editing area has two types of register value notation and register value conversion notation.
T hey are synchronized.
When you click the [Write] button arranged in each item, the changed data is written to GXE.

Overview
Difital CV
Set the reference value of the output voltage when the digital CV function is enabled.
In the display area, the left side is the register data
and the right side is the voltage conversion value.
T he register data is the normalized reference value with the nominal voltage [Q10 format *]
T he register value can be set within the range of 0.0 [Q10] to 1.3 [Q10].
(1.3 times the nominal voltage is the upper limit)
If a value out of upper range is entered, 1.3 [Q10] is set.
Product specifications range from 0.2 to 1.2 times the nominal voltage.
Factory setting : 1.0[Q10] (1.0 times the nominal value)
Digital CC
Set the reference value of the output current when the digital CC function is enabled.
In the display area, the left side is the register data
and the right side is the current conversion value.
T he register data is the normalized reference value with the maximum current[Q10 format]
T he register value can be set within the range of 0.0 [Q10] to 1.15 [Q10].
(1.15 times the maximum current is the upper limit)
If a value out of upper range is entered, 1.15 [Q10] is set.
Product specifications range from 0.2 to 1.15 times the maximum current.
Factory setting : 1.15[Q10] (1.15 times the maximum current)
OVP Threshold
Set detection threshold of SWOVP (software overvoltage protection).
In the display area, the left side is the register data
and the right side is the voltage conversion value.
Register data is normalized with threshold of nominal voltage [Q10 format]
T he register value can be set within the range of 0.2 [Q10] to 1.25 [Q10].
(1.25 times the nominal voltage is the upper limit)
If a value out of upper range is entered, 1.25 [Q10] is set.
Factory setting : 1.25[Q10] (1.25 times the nominal voltage)
OCP Threshold
Set detection threshold of SWOCP (software overcurrent protection).
In the display area, the left side is the register data
and the right side is the current conversion value.
Register data is normalized with threshold of nominal current [Q10 format]
T he register value can be set within the range of 0.2 [Q10] to 1.20 [Q10].
(1.20 times the maximum current is the upper limit)
If a value out of upper range is entered, 1.20 [Q10] is set.
Factory setting : 1.20[Q10] (1.2 times the nominal current)
T o enable SWOCP, set the threshold smaller the CC reference value.
* For the Q10 format, refer to "5.3 Q format data".
