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, filtered 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, filtered 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 .
