In the constant output area (output frequency > Max. Voltage Output
Frequency (n11)), the stall prevention (current limit) level during
acceleration is automatically decreased using the following equa-
tion.
Stall prevention (current limit) level during
acceleration in constant output area
Stall prevention (current limit)
level during acceleration (n56)
Stall Prevention Level
during Acceleration
Stall Prevention (Current Limit) Level while Running (n57)
Sets the stall prevention (current limit) level while running in units of
1%. (Inverter rated current = 100%)
Factory setting: 160%
A setting of 200% disables stall prevention (current limit) while run-
ning.
If the stall prevention action current at speed agreement exceeds the
value set for n57 for longer than 100 ms, deceleration starts.
If the output current exceeds the value set for n57, deceleration contin-
ues. If the output current goes to the value set for n57, acceleration to
the set frequency starts.
Stall prevention acceleration/deceleration settings during operation are
set either for the currently selected Acceleration Time, i.e., for Acceler-
