Compliment Description For Energy-Saving Functions - Sanken SAMCO-NS Series Instruction Manual

◆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.
