Automatic Energy-saving Selection
Default: 0
Settings 0: Disable
1: Enable
When energy-saving is enabled, the motor acceleration operates with full voltage. During
constant speed operation, it automatically calculates the best voltage value according to the load
power. This function is not suitable for fluctuating loads or loads that are nearly full during
operation.
When the output frequency is constant (that is, constant operation), the output voltage decreases
automatically as the load decreases. Therefore, the drive operates with minimum multiplication of
voltage and current (electric power).
FOCPG IM:
Steady-speed: Torque current is lower than rated current for 0.35 times and entry into energy
saving mode after 5 seconds.
Return: Torque current is higher than 0.5 times of rated current.
VF, VFPG, SVC mode:
Steady-speed: When output is light load, entry into energy saving mode after 5 seconds.
Return: When the drive is continuously adding loads, or in non-steady speed status.
FOCPM and FOC sensorless control mode, disable.
