5.3.7 Output peak current limiter settings
The positive value and the negative value of the peak current limiter can be set independently.
If the output peak current exceeds the set current, the output voltage is clipped.
Setting range limits can be set for output voltage and output frequency.
See “5.5.5 Setting range limiter (LIMIT)”
.

Limiter settings are retained separately for the 100 V and 200 V range.
Since these are not fully constant current operations, the specified limit value may not be achieved,
depending on the load.

ee “3.4.7 Using limiter functions”
, for description of the output peak current limiter settings.
Note with caution that the output peak current limiter may allow overshooting, depending on the load,
and therefore may not achieve the peak current value as set.
For an inductive load, operation of the limiter can cause an output overvoltage, triggering the
protection function. In this case, the peak current limiter settings (positive and negative) should be
reduced.
