Daikin ACS320 - Program Features; Programmable Analog Inputs; Programmable Analog Output

program feaTures
This section describes program features. For each feature, there is a list of related user settings, actual signals, and
fault and alarm messages.
Programmable Analog Inputs
The drive has two programmable analog voltage/current
inputs. The inputs can be inverted, ltered and the maximum
and minimum values can be adjusted. The update cycle for
the analog input is 8 ms (12 ms cycle once per second). The
cycle time is shorter when information is transferred to the
application program (8 ms -> 2 ms).

Programmable Analog Output
One programmable current output (0…20 mA) is available.
Analog output signal can be inverted, ltered and the maximum
and minimum values can be adjusted. The analog output
signals can be proportional to motor speed, output frequency,
output current, motor torque, motor power, etc. The update
cycle for the analog output is 2 ms.
It is also possible to write a value to an analog output through a
serial communication link.
