Load Current Limit (Constant-current Models Only)
The load current limit function is used to measure the load current with the
built-in CT and to limit the load current by adjusting the output phase angle so
that the load current does not exceed the value set in the Load Current Upper
Limit parameter [P10].
• The load current upper limit is set in the Load Current Upper Limit param-
eter [P10] in the initial setting level.
• This function can be used with Constant-current Models only.
• When this function is being used, the output value that is actually output
will be smaller than the output value that is calculated based on the input
value.
• The following example shows the load current limit function used when
the maximum load current is 20 A.
!Caution
The load current limit function cannot be used to suppress the inrush current
for loads with a large inrush current. For loads with a large inrush current, use
the load current limit function together with the soft-start up function to sup-
press the inrush current. The response time that is required before the load
current can be suppressed is 500 ms max.
