Daikin ACS320 User Manual

Supervisions
The drive monitors whether certain user selectable variables
are within the user-dened limits. The user may set limits for
speed, current etc. The supervision status can be indicated
through relay or digital output.
The supervision function outputs can be used for triggering
some drive functionality (start/stop, sleep, pump cleaning).
The supervision functions operate on a 2 ms time level.

Energy Optimizer
Energy optimizer optimizes the ux so that the total energy
consumption and motor noise level are reduced when the drive
operates below the nominal load. The total efciency (motor
and drive) can be improved by 1…10% depending on load
torque and speed.
Energy saving tools calculate energy saved in kWh and MWh,
energy saved in local currency as well as reduction in CO
2
emission, all compared to the situation when the pump is
connected directly to the supply.
