Instruction manual

• Stall prevention (current limit) level during running (n094)
Sets the stall prevention (current limit) level during running in units of 1%.
(Inverter rated current = 100%)
Factory setting: 160%
A setting of 200% disables the stall prevention (current limit) during
running.
If stall prevention action current at agreed speed exceeds the value set for
n094 for longer than 100msec, deceleration starts.
When the output current exceeds the value set for n094, deceleration
continues. When the output current goes down to the value set for n094,
acceleration starts, up to the set frequency.
Stall prevention accel/decel settings during operation are set either by
currently-selected acceleration time 1 (n019) and deceleration time 1
(n020), or acceleration time 2 (n021) and deceleration time 2 (n022).
*Decreases frequency to prevent the motor
from stalling.
†At acceleration start, output current hysterisis
is approx. 5% of inverter rated current.
• Stall Prevention automatic decreace selection (n115)
The stall prevention level can be decreased automatically in the constant
output range.
