Filter Settings
The equipment includes two filters: a low-pass analog filter incorporated into an analog circuit and a
stabilizing digital filter that processes the torque or rotation signals acquired.
CAUTION
The digital filter affects both the digital output and analog output.
The analog filter affects only the analog output.
Inappropriate filter settings may result in incorrect measurements and unforeseen accidents.
Torque Analog Filter
The torque analog filter lets you adjust the responsiveness of the analog output for torque (voltage and
current output).
With this equipment, the torque analog filter can be set to one of nine levels: 1 Hz, 10 Hz, 30 Hz, 50 Hz,
100 Hz, 300 Hz, 500 Hz, 1 kHz, or 6 kHz.
This can be set using function mode F-05.
By default, [1 kHz] is selected when function mode F-54 is 0, and [6 kHz] is selected when F-54 is 1.
For details of the operating procedure, see "9. Function Mode".
Frequencies tend to have the following characteristics:

6 kHz
Noise resistance
Response speed
Stable
Sensitive
Slow
Fast
Torque Digital Filter
The torque digital filter provides stability through moving-average processing of input torque values.
With this equipment, the torque digital filter can be set from [00] to [88].
The value set determines the number of moving-average samples for the torque digital filter.
This can be set using function mode F-06.
By default, this is set to [00]. For details of the operating procedure, see "9. Function Mode".
The correlation between the setting and the number of moving-average samples is given approximately
by the following equation:
(No. of moving-average samples) = 2

For example, if the setting is [55], the approximate number of moving-average samples will be as
follows:

The number of moving-average samples tends to have the following characteristics:
