Parameterising channel parameters
Manual mode when kinematic transformation is active
Additional Cartesian dynamic limits are available in conjunction with kinematic transformation, i.e. they act on Cartesian position axes and orientation axes.
Typical application examples are in the field of non-linear kinematics (e.g. robots) where the PCS limits (Cartesian programming coordinates) and ACS limits (axis coordinates) can have large differences.
Position axes: (typical axis index 0 to 2)
P-CHAN-00195: maximum velocity
P-CHAN-00196: maximum acceleration
P-CHAN-00197 Ramp time
Orientation axes: (typical axis index 3 to 5)
P-CHAN-00198: maximum velocity
P-CHAN-00199: maximum acceleration
P-CHAN-00200: Ramp time

Notice
Due to the distance accuracy of the manual mode, the maximum permissible velocity in handwheel mode must be set to avoid unnecessarily long motion delay in handwheel mode. Therefore, the distance specified for each CNC cycle should not exceed the maximum velocity.
In the same way the incremental jog velocities must be aligned with the maximum permissible velocity in manual mode to avoid unnecessarily long motion delay after pressing the jog keys. With relatively small acceleration values, a certain delay time inevitably occurs after the jog key is released.
