Actual Signals; Power Loss Ride-Through - Daikin ACS320 Operation Manual

Actual Signals

Several actual signals are available:
• Drive output frequency, current, voltage and power
• Motor speed and torque
• Circuit DC voltage
• Active control location (LOCAL, EXT1 or EXT2)
• Drive temperature
• Operating time counter (h), kWh counter
• Digital I/O and analog I/O status
Three signals can be shown simultaneously on the assistant
control panel display (one signal on the basic panel display) .
It is also possible to read the values through the serial
communication link or through the analog outputs .

Power Loss Ride-Through

If the incoming supply voltage is cut off, the drive will continue
to operate by utilizing the kinetic energy of the rotating motor .
The drive will be fully operational as long as the motor rotates
and generates energy to the drive . The drive can continue
the operation after the break if the main contactor remained
closed .
