Function extension
The upper and lower speed limits (lrVelocitylowLimit, lrVelocityHighLimit) can now be parameterized to values with the same sign.
The new >FB input 'xAllowSameSignVelocityLimit' must be set to TRUE for this.
Note
If both limit values have the same sign, the standstill is not included in the value range.
Immediately after controller enable, the axis therefore accelerates to the speed threshold parameterized at the lrVelocityLowLimit input.
This parameterization is only useful for applications in which the axis is to be in constant motion.
Included in the following products:
Library:L_MC1P_MotionControlBasic (FAST Motion) from V03.33.xx (planned)
Application:
Applications in which the axis should/must be in constant motion.
Short-term measure for previous versions:
FB-Propterty ValidateSpeedLimits:
By setting the FB-Propterty 'ValidateSpeedLimits' := False, the check for the same sign be deactivated.
Positive values for the FB input lrVelocitylowLimit and negative values for the FB input lrVelocityHighLimit are then permitted.
