•
Stall prevention (current limit) level during running (n094)
Sets the stall prevention (current limit) level during running in units of 1% (Inverter
current = 100%).
•
Factory setting: 160%
A setting of 200% disables the stall prevention (current limit) during running.
If the inverter is at speed agree and output current exceeds the value set for n094 for
longer than 100msec, deceleration starts.
Deceleration continues until the output current falls below the value set for n094.
When this occurs, the inverter will accelerate back up to the set frequency.
Stall prevention accel/decel settings during operation are set either by accel time 1
(n019) and decel time 1 (n020), or accel time 2 (n021) and decel time 2 (n022).

Stall prevention automatic decrease selection (n115)

range.

* Decreases frequency to prevent the motor
from stalling.
† At acceleration start, output hysteresis is
approx. 5% of inverter rated current.
