5 Motor Evaluation and Auxiliary Input (Option)
Motor Evaluation/Auxiliary Inputs (Motor/Aux)
Motor Evaluation Function
This instrument can determine the motor rotating speed, torque, and output. It determines them using the
revolution sensor signal, which is proportional to the motor rotating speed, and the torque meter signal, which
is proportional to the motor torque. You can configure this instrument to receive analog (DC voltage) signals or
pulse signals from the revolution sensor and torque meter. Also, you can set the number of motor poles and
determine the motor’s synchronous speed and slip. Furthermore, you can use the active power, frequency, and
motor output measured by this instrument to compute the motor efficiency and total efficiency.
For a list of the measurement functions that can be measured with the motor evaluation feature and their
descriptions, see “Motor Evaluation Functions” under “Items That This Instrument Can Measure.”
Auxiliary Input
You can apply signals from illuminance sensors, wind sensors, temperature sensors, and the like and display
these physical quantities.
Motor/Auxiliary Input Displays
The motor/auxiliary input settings are displayed on the Options tab in the input information area on the right side
of the screen. The following figure shows a display example when motor evaluation function 1 is set to single
motor (revolution signal, pulse) and motor evaluation function 2 is set to auxiliary input (Aux).
