SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
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
MD32200: POSCTRL_GAIN
=
Traverse rate
– Desired following error [mm]
– Traversing velocity [m/min]
– MD32200: POSCTRL_GAIN (Kv factor) [(m/min)/mm]
The actual following error is shown in the axis–specific service data:
