Tune Acceleration/Deceleration
Time
The Tune Acceleration Time and Tune Deceleration Time attributes return
acceleration and deceleration time in seconds for the last run MRAT (Motion
Run Axis Tune) instruction. These values are used to calculate the Tune
Acceleration and Tune Deceleration attributes.
Tune Acceleration/Deceleration
The Tune Acceleration Time and Tune Deceleration attributes return the
measured acceleration and deceleration values for the last run MRAT (Motion
Run Axis Tuning) instruction. These values are used, in the case of an external
torque servo drive configuration, to calculate the Tune Inertia value of the axis,
and are also typically used by a subsequent MAAT (Motion Apply Axis Tune)
to determine the tuned values for the Maximum Acceleration and Maximum
Deceleration attributes.
Tune Speed Scaling
The Tune Speed Scaling attribute returns the axis drive scaling factor measured
during the last executed MRAT (Motion Run Axis Tune) instruction. This
value is only applicable to axes configured for interface to an external velocity
servo drive. In this case, the Tune Speed Scaling attribute value is directly
applied to the Velocity Scaling attribute by a subsequent MAAT (Motion
Apply Axis Tune) instruction.
Tune Rise Time
The Tune Rise Time attribute returns the axis rise time as measured during the
last executed MRAT (Motion Run Axis Tune) instruction. This value is only
applicable to axes configured for interface to an external velocity servo drive.
In this case, the Tune Rise Time attribute value is used to calculate the Tune
Velocity Bandwidth.
