Parameters and firmware blocks

Group
Settings for the analogue outputs.
The drive offers two programmable analogue outputs: one current output AO1
(0…20 mA) and one voltage output AO2 (-10…10 V).
The resolution of the analogue outputs is 11 bits (+ sign) and the inaccuracy is 2% of
the full scale range.
The analogue output signals can be proportional to motor speed, process speed
(scaled motor speed), output frequency, output current, motor torque, motor power,
etc. It is possible to write a value to an analogue output through a serial
communication link (e.g. fieldbus link).

15 ANALOGUE OUTPUTS
Firmware block:
AO1
(14)
Connects an actual signal to
analogue output AO1, and filters and
scales the output signal. Also shows
the value of the output.

AO1 PTR
FW block:
(see above)
Selects a drive signal to be connected to analogue output AO1.
Value pointer: Group and index
15.02
AO1 FILT TIME
FW block:
(see above)
Defines the filtering time constant for analogue output AO1.
Note:
The signal is also filtered due to the signal interface hardware (approximately 0.5 ms time
constant). This cannot be changed by any parameter.
0…30 s
Filter time constant for AO1.

AO1 MAX
FW block:
(see above)
Defines the maximum value for analogue output AO1.
