Motor Measurement (Motor Analysis-Equipped Model)
Configuring the motor input settings
Connect torque sensors and tachometers by referring to “Motor measurement wiring” (p. 78).
Configure the motor analysis settings based on those connections.

box, and select the frequency from the
list.
Set this when pulses are to be input for the
motor input.

Upper frequency limit
This setting specifies the lowest frequency that exceeds the maximum frequency of the input pulse signal.
When [Motor analysis option wiring] is set to [Individual Input] , the setting is used as the upper limit for
D/A output.
When using motor analysis mode, this setting is used as the pulse frequency that is used to display RPMs and
motor powers and as a pulse frequency to calculate the upper limit value for the D/A output.

If the input RMS signal setting is [Analog] , the RMS upper limit is calculated by multiplying the scaled RMS
value by the voltage range value.
Lower frequency limit
This setting specifies the lower frequency limit for measurement of the input pulse signal.
When the following synchronization sources are selected, the lower limit frequency is also used as the lower
frequency limit for measurement.
