Trigger Mode

Trigger is a function of updating and monitoring the measured 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 con-
stant speed avoiding the state where the motor is stopped or accelerating or decelerating. Depending
on the application, select the trigger mode from Always (while power is ON), External Trigger, or Inter-
nal Trigger. The operation of each trigger mode is shown in the table below.
