Checks
Check of the position controller setting
The position controller settings can be easily managed via the service axis display.
The number 1 (corresponds to servo gain = 1) should be entered in machine data:
MD32200 $MA_POSCTRL_GAIN [n] (servo gain factor).
The change takes effect immediately.
Because the servo gain factor is defined as
6HUYRJDLQIDFWRU
6SHHGVHWSRLQW
)ROORZLQJHUURU
>PPLQ@
>PP@
'HIDXOW
a following error of 1 mm must be measured (with KV = 1 and constant velocity) at a
feedrate of 1 m/min.
If the desired servo gain (KV) factor does not correspond to the actual factor, the possible
causes and remedial optimization options are as follows:
•
Speed or torque feedforward control is activated. A higher servo gain factor is displayed
than was set with machine data:
MD32200 $MA_POSCTRL_GAIN [n] (servo gain factor)
.
•
Filter for jerk limitation or dynamic response adaptation is activated. A lower servo gain
factor is displayed than was set with machine data:
MD32200 $MA_POSCTRL_GAIN [n] (servo gain factor)
.
