• Stall prevention (current limit) level during running (n57)
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 output current during speed agree exceeds the value set for n57 for longer than
100msec, deceleration starts.
As long as the output current exceeds the value set for n57 deceleration continues.
When the output current goes below the value set for n57, acceleration begins to the set
frequency.
The accel/decel rates during stall prevention are determined by the accel time (n16 or
n18) and decel time (n17 or n19) that is selected at the time of the stall prevention
condition.
• Stall prevention (current limit) function during deceleration (n55)
To prevent overvoltage during deceleration, the inverter automatically lengthen the
deceleration time according to the value of main circuit DC voltage.

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