5.2 Reference Unit

Reference Unit
Here describes the reference unit.
The data of measurement target has each unit, as shown in Table 5-1.
Table 5-1: Unit of Data
Data type Unit
Speed [rpm]
reference Rotating speed of target axis motor in a minute
Speed [rpm]
feedback Actual rotating speed of target axis motor in one minute
Torque [%]
reference Current torque reference value when the target axis motor rated
torque is converted as 100%.
Concurrent I/O No unit, for it is just an ON/OFF signal.
To differentiate from other signal data, [U] (unit) is used for
expediency.
OFF: 0 U is output
ON: 1.0 U is output
Register No unit, for it is just an register value.
Register value is output without changed.
Example: When the vertical scale is 100[-/div] and the target
register value is 200, the output of 2 divisions is given
When the speed reference is selected as a measurement signal of the
target channel, the initial value of the reference unit is 1000 [rpm/div].
This means that the speed is 1000 [rpm] when the output of vertical 1 [div]
is given from the target channel zero position. From this relationship, the
outline of waveform data output on the waveform display area can be
grasped.
Example: with the setting of 1000 [rpm/div]:
Output of 2.0 [div]:
Output of -3.3 [div]:
Since the reference unit can be changed in the {ChCondition} tab, the
waveform display scale in the vertical direction can be changed
accordingly.
Example: with the actual output of 1000 [rpm]:
Setting of 1000 [rpm/div]:
Setting of 500 [rpm/div]:
5-2
2000 [rpm]
-3300 [rpm]
Output of 1 division
Output of 2 divisions
