Using Limiter, Setting Limiter
4.1.1 Use Peak Current Limiter
Peak value of output current is limited by the peak current limiter. While the limiter is working, icon
is displayed and LIMIT LED illuminates.
Setting values of peak current limiter are variable, and kept independently for each of 100 V and 200
V ranges.
You can choose whether to make the output off or not upon the triggering of the peak current limiter.
If you choose to set the output off, specify the continuous operation time of limiter until the output
off becomes effective. Whether output off is set or not and the time setting are common regardless
of the output ranges.
For the default setting range, see
10.13
.

Notes
------------------------------------------------------------------------------------------------------------
Output current value may be limited by a value that is different from the setting value,
depending on the load.
For an inductive load, overvoltage protection may be triggered due to the operation of peak
current limiter. Overvoltage protection may be avoided by lowering the limiter setting value
both for negative and positive values.
When the number of power units that are energized is increased or decreased based on the
power unit energization setting, the setting values of the peak current limiter are reset to the
factory default setting corresponding to the ratings output power.
In the polyphase system, the setting of the peak current limiter is common to all phases.
If the output off after the continuous operation of the limiter for the specified duration is
enabled, the setting of output-off phase is ignored.
In the case that the peak current limiter operates when the setting value of the peak current
limiter is set as asymmetry between positive and negative in the AC mode, the DC component
is generated in the output. Although the function to remove the DC component of the output
works in the AC mode, when the peak current limiter operates intermittently, the DC
component may not be removed sufficiently, or the output waveform may be modified.

Operation procedure
1.
Push [Limiter] soft-key to select 1: Ipk Limiter (or push
+
). Opens the peak
current limiter set window.
