Intelligent mode selection (Pr. 60)

Pr. 60 "intelligent mode selection"
The inverter automatically sets appropriate parameters for operation.
If you do not set the acceleration and deceleration times and V/F pattern, you can run the inverter as if
z
appropriate values had been set in the corresponding parameters. This operation mode is useful to start
operation immediately without making fine parameter settings.

Set to accelerate/decelerate the motor in the shortest time. The
inverter makes acceleration/deceleration in the shortest time using its full
capabilities. During deceleration, an insufficient brake capability may cause
the regenerative overvoltage alarm (E.OV3).
"1": Stall prevention operation level 150%
"2": Stall prevention operation level 180%
Optimum operation can be carried out by fully utilizing the inverter
capabilities in the continuous rating range.
Self-learning automatically sets the corresponding parameters so that the
average current during acceleration/deceleration is equal to the rated current.
Appropriate for applications where the load will not vary by a large ammount.
Tunes the inverter output voltage online to minimize the inverter
output voltage during constant-speed operation.
Appropriate for energy-saving applications such as fan and pump.
Automatically controls the inverter output voltage to deliver the
maximum torque in both the driving and regenerative modes. Appropriate
for a counterbalanced elevator.
"5": Stall prevention operation level 150%
"6": Stall prevention operation level 180%
