Intelligent Mode Selection (Pr. 60) - Mitsubishi Electric FR-F500 Instruction Manual

4.2.26 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.

Note: 1. When more accurate control is required for your application, set the other parameters as
appropriate.
2. Because of the learning system, this control is not valid at the first time in the optimum
acceleration/deceleration mode. Also, this mode is only valid for frequency setting of 30.01Hz or
more.
3. If an overvoltage (OV3) trip has occurred during operation in the optimum
acceleration/deceleration mode (setting "3"), re-set Pr. 8 "deceleration time" to a larger value and
restart operation in this mode.
4. When "4" (energy-saving mode) or "9" (optimum excitation control mode) has been set to
decelerate the motor to a stop, the deceleration time may be longer than the preset value.
Because overvoltage is more likely to occur in this mode when compared to constant torque load
characteristics, set the deceleration time to a longer value.
Setting Range
0, 3, 4, 9
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.
Optimizes the exciting current as an energy-saving technique to maximize the
motor efficiency. Appropriate for further energy-saving applications such as
machines which are large in GD
