Trigger Mode

Trigger is a function of updating and monitoring the measurement values when certain conditions are
met. To observe the aging of the motor, it is necessary to set the installation state, load, and rotation
speed of the motor during measurement to the same condition, and to measure the motor rotating at a
constant speed avoiding the state where the motor is stopped or accelerating or decelerating. Depend-
ing on the application, select the trigger mode from Free run (while power is ON), External Trigger, or
Internal Trigger. The operation of each trigger mode is shown in the table below.
