Incorrect speed setpoint matching has a negative impact on the real servo gain
of the axis.
To check speed setpoint matching it is necessary for a defined traverse velocity
to compare the actual following error with the desired following error that should
be set if speed setpoint matching is correct.
=
Desired following error
–
Desired following error [ mm ]
–
Traversing velocity [ m/min ]
–
MD32200: POSCTRL_GAIN (KV factor) [ (m/min)/mm ]
The actual following error is displayed in the axis-specific service data:
