Monitoring Delay Settings
To observe the aging of the motor, it is necessary to set the condition of the motor at measurement to
the same condition, and to measure the motor in a stable state avoiding the state where the motor is
stopped or accelerating or decelerating. Start measurement at the appropriate timing by setting the
monitoring delay time in reference to the following.
1
Determination of trigger mode
Refer to 3-2-4 Trigger Mode on page 3-5 and decide the trigger mode and trigger type according
to the application.
2
Determination of moving average times
Reducing the moving average times can help capture instantaneous fluctuations.
Increasing the moving average times can suppress the steep fluctuation of measurement val-
ues and capture the overall trend.
Determine the moving average times of measurement values according to the state of measure-
ment value.
3
Determination of monitoring delay time (when trigger mode is external trigger or internal trigger)
To obtain the measurement value when the state of the motor is stable, set the monitoring delay
time using the following calculation formula.
Time to wait for motor to stabilize
*1 Time until the rotation speed stabilizes after the motor rotation speed is increased or
decreased (during startup or changing of rotation speed).
*2 The sampling period differs for each measured target. For details, refer to 3-2-1 Sampling of
measurement values on page 3-3.
*3 Set this as 1 when the moving average times setting is OFF.
