3.5.1 Manual Setting of N-0 Compensation Values
Example: Setting N-0 compensation value for the CW direction
Prepare the following table, rotate the detection shaft using a motor, etc., then record the torque display
value for each rpm.
Note: Like zero compensation, enter display values, with the decimal point removed, in the
count column. This also applies to rpm display values.
Then, plot values using the horizontal axis for the rpm and the vertical axis for the torque display value to
determine compensation points.
The detector can be thought to have the frequency characteristic shown by the broken line shown below.
When approximation is made linearly using 4 compensation points, Nos.1 to 4 are selected. In the above
example, when more data are taken around 2000r/min where the curve largely changes, compensation
values can be set more finely resulting in more accurate measurement.
