8.1.7 Adjustment

Due to component tolerance, it can be necessary to adjust the analog input. This is
done via parameter
Adjustment
0 - No adjustment
1 - Adjustment 0 V
2 - Adjustment 10 V

8.1.8 Filter time constant

The time constant of the filter for the reference analog value can be set via the para-
meter
Filter time constant
The time constant indicates the time during which the input signal is averaged by
means of a low pass filter, e.g. in order to eliminate fault effects.
The setting range is between 0 ms and 5000 ms in 15 steps.
Filter time constant
0 - Time constant 0 ms
2 - Time constant 2 ms
4 - Time constant 4 ms
8 - Time constant 8 ms
16 - Time constant 16 ms
32 - Time constant 32 ms
64 - Time constant 64 ms
128 - Time constant 128 ms
256 - Time constant 256 ms
512 - Time constant 512 ms
1000 - Time constant 1000 ms
2000 - Time constant 2000 ms
3000 - Time constant 3000 ms
4000 - Time constant 4000 ms
5000 - Time constant 5000 ms

Standard operation
Adjustment of the measurement with an analog signal
of 0 V.
Adjustment of the measurement with an analog signal
of 10 V.
The measurements for the adjustment are to be done with a suitable
measuring instrument and the correct polarity.
If not, faulty measurements can result.
Apply 0 V to the analog input; e.g. with a bridge from the terminal of the ana-
log input X410A.6 to terminal X210B.7 (earth/GND) of the frequency inverter.
Select operation mode "1 - Adjustment 0 V".
Apply 10 V to the analog input, e.g. with a bridge from the terminal of the
analog input to terminal X210B.5 (reference output 10 V) of the frequency in-
verter.
Select operation mode "2 - Adjustment 10 V". This completes the adjustment
of the analog input.
