Current Limit (Stall Prevention)
This function automatically adjusts the output frequency in response to an
increase in load current to continue operation without tripping the
inverter.
·Stall Prevention Level During Acceleration (n073, StallP Accel Lvl)
The current limit level during acceleration can be set in units of 1%
(inverter rated current = 100%).
Factory setting: kVA dependent
A setting of 200% disables current limit during acceleration. During
acceleration, if the output current exceeds the value set for n073, accel-
eration stops and frequency is maintained. When the output current
goes down below the value set for parameter n073, acceleration
resumes at the normal acceleration rate.
