r/min 2 yes
Description
Indicates the command value being input from the position loop (in Position Control mode)
or analog speed command (in Analog Speed Control mode) to the speed loop.
While tuning, by measuring this value (waveform data displayed in "Servo Studio") and
position deviation (or speed deviation) at the same time, you can check command response
with positioning time and vibration.
Verify that no commands with extremely short acceleration/deceleration time are input
from the host controller.
If a command's acceleration/deceleration time is too short, the motor will be unable to
keep up and vibration will easily occur.
If you want to set a short acceleration/deceleration time, use a position command smoothing filter.
