In the constant output area [output frequency ≥ base frequency (n013)],
the current limit level during acceleration is changed by the following
equation:
·Stall Prevention Level During Running (n074, StallP Run Level)
The stall prevention level during running can be set in units of 1%
(inverter rated current = 100%).
Factory setting: kVA dependent
A setting of 200% disables current limit during running. During speed
agree, if the output current exceeds the value set for parameter n074,
then deceleration is initiated.
While the output current exceeds the value set for n074, deceleration
continues. When the output current goes below the value set for param-
eter n074, acceleration begins at the normal acceleration rate bringing
the motor to the set frequency.
