"intelligent mode selection"
By selecting this parameter, the inverter is automatically ad-
justed as if the appropriate value had been set in each parame-
ter, without needing to set the acceleration and deceleration
times and V/F pattern. This operation mode is useful to perform
operation immediately without making fine parameter settings.

Operation
The self-learning system
automatically sets the boos
value, acceleration and de
celeration times so that the
current during acceleration,

Note: 1. When more accurate control is required for application, set
parameters manually.
2. Because of the learning system, this control is not valid the
first time.
3. If an overvoltage (OV3) trip has occurred during operation in
the optimum acceleration/deceleration mode, reset Pr. 8 "de-
celeration timen t o a slightly larger value and restart opera-
tion in this mode.
4. When either of "3 or 4" has been set in Pr. 60, the parameters
dedicated to intelligent mode Pr. 61 to 63 are valid.
Pr. 61 to 64, which need not be set unless required, may be
set to improve performance. Set "0" in Pr. 60 to automatically
set "9999" (factory setting) in Pr. 61 to 63.
5. When the motor is decelerated to a stop in the energy-saving
mode, the deceleration time may become longer than the
setting.
Also, since an overvoltage is more likely t o occur in this mode
than in the constant-torque load characteristic, set a longer
deceleration time.
6. The optimum acceleration/deceleration mode is only valid for
the frequency setting of 30.01Hz or higher.
