(Note-1): The motor speed that took the average every 227[ms].
Use the servo amplifiers of version compatible with the monitor of motor speed.
Always "0" if the monitor is executed for the servo amplifier which does not support this
function.
(Note-2): The data set to "Droop pulse monitor selection for controller display" of "
Fully closed loop
function selection 3
(PE10)" is monitored.
(Note-3): It can be monitored when using the linear servo motors.
(Note-4): It can be monitored when using the fully closed control.
(Note-5): It can be monitored when using the synchronous encoder via servo amplifier.
Refer to each servo amplifier instruction manual for details of the data monitored.
