Functions
Automatic Energy-saving Operation Function
• This function automatically minimizes the Inverter output power during constant speed operation,
and is suitable for load with reduced torque characteristics (e.g. fan, pump).
• To operate with this function, set RUN mode selection A085 to "01".
You can adjust the response and accuracy with energy-saving response/accuracy adjustment
A086.
• Controls the output power at a comparatively slow rate. Should rapid load fluctuation like impact
load occur, the motor may stall, resulting in an overcurrent trip.
Automatic Optimum Acceleration/Deceleration
• The automatic acceleration/deceleration function eliminates the need for acceleration/deceleration
settings during Inverter operation.
• Conventionally, the user had to set an Inverter acceleration/deceleration time depending on the
actual load conditions. However, this function can automatically set an acceleration/deceleration
time, making full use of the Inverter's capacity.
The acceleration time is a time during which acceleration is performed within a current value set in
the overload limit parameter (when the overload limit function is enabled), or within approx. 150%
of the rated current (when the overload limit function is disabled). The deceleration time is a time
during which deceleration is performed within approx. 150% of the rated current value, or within a
DC voltage in the Inverter circuit of approx. 370 V (200V-class) or approx. 740 V (400 V-class).
Thus, the Inverter enables real-time response to a change in applied load and inertia, and sets
acceleration/deceleration time automatically.
• Note the following before use:
Note 1: This function is not suitable for a machine that needs a fixed acceleration/deceleration time.
Acceleration/deceleration time varies depending on applied load and inertia.
Note 2: If the machine inertia exceeds approx. 20 times that of the motor shaft, the Inverter may trip.
In this case, reduce the carrier frequency.
