Setting The Limit For Set Position P324; Kinematic Transformation Of Skew Drive Position, Angle Of Rotation - Siemens SIMOTION D4x5-2 DP/PN Operating Instructions Manual

Perform the following steps:
1. Inching movement with the skew axis
Start an inching movement with the skew axis over a fairly long path with P328 set to its
default value.
Please note:
– Constant travel should take several seconds.
– A sufficient distance from the end positions is absolutely necessary to be able to stop
– The setpoint and target positions must be virtually identical at the end.
Possible causes of greater deviations:
– Incorrect maximum output velocity or
– Limitations in the drive system
2. Optimizing the position controller
– Set the position controller such that slight overshooting occurs.
– If the velocity curve exhibits oscillations and the actual position overshoots at the target
3. Parameterize "motion_terminated_ska"
Via parameters P329 (positioning accuracy skew drive), P330 (switch-on delay
"motion_terminated_SkA skew drive"), and P331 (zero-speed measurement skew drive),
setting status bit "motion_terminated_ska" (motion terminated) is set.

Setting the limit for set position P324

This value limits the position setpoint that is output by the skew control.
P324 = Set maximum position for skew drive (spindle)

Kinematic transformation of skew drive position, angle of rotation

Determine the angle of rotation resulting from the position and transformation factor P327 in
this way:
Angle of rotation [cgr] = s_act_SkA · P327

motion in time if an error occurs.
This affects the current velocity and the current position. Short rise times can be
achieved in this way.
position, reduce the value.
Note
An overshoot at the target position often occurs because the maximum velocity is set
incorrectly and not because the proportional gain of the position controller is too high.
Before the position controller is reduced, the actual velocity should therefore be checked
again in travel at constant velocity to determine whether it approximately matches the
output velocity.
