(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 setting 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 direct drive motors.
(Note-5): It can be monitored when using the fully closed control.
Refer to the "Servo amplifier Instruction Manual" for details of the data monitored.
