4.2.25 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
appropriate values had been set in the corresponding parameters. This operation mode is useful to start
operation immediately without making fine parameter settings.
If the intelligent operation mode has been selected, entry of the jog signal or RT (second function
selection) signal during an inverter stop starts ordinary operation, with priority given to jog operation or
second function selection. After a start in the intelligent operation mode, neither the JOG signal nor the RT
signal is accepted.

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 amount.
Tunes the output voltage online to minimize the inverter output power during
constant-speed operation.
Appropriate for energy-saving applications such as fan and pump operation.
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%
