◆
Auto saving control is effective during constant torque operation. When rated speed has been exceeded
during constant power operation, a weak magnectic control will be adpted as normal modes.
■
Compliment description for energy-saving functions
◆
On the occasion of energy-saving
、
Motor speed control
、
the others feedback control using at the same
time, enginer-saving function could be executed with PID control functio if the system was installed
sensor.
◆
The better performace for the square torque loading, such as fan
、
pump and the others light load, but it
is not valuable in energy-saving for constant torque loading of heavy load.
◆
Re-set auto energy-saving function under re-start through Flying function
、
Alarm auto-recovery
function
、
Momentary re-starting function.
◆
Action of energy-saving is effective during constant speed operation of stable loading torque(frequency
matching condition). Therefore, on the occasions of frequency setting throught analog frequency input,
Energy-saving is effective for slowly change of freuency setting through increasing frequency
matching range (F1508
)
.
◆
On the occasions of F1001=2
、
3 (Speed Control Mode), the speed should be compensated during
energy saving.
