MDS-D-SVJ3/SPJ3 Series Instruction Manual
5-2 Adjustment procedures for each control
5-2-4 Orientation adjustment
Adjusts orientation time by adjusting SP016.
(1)Orientation characteristics
When decelerating to stop is executed with orientation, the remaining distance to the orientation stop
position is compensated within one rotation. Thus, as shown in Case 1 below, when the remaining
distance in deceleration is about "0", orientation time would be the shortest (time required to decelerate
and stop + 0s), and as shown in Case 2 below, when the remaining distance in deceleration is about as
much as one rotation amount, orientation time would be the longest.
【#13016】 SP016 DDT Phase alignment deceleration rate
Set the single-rotation position alignment deceleration rate for orientation stopping, phase alignment
while rotating and switching from non-interpolation mode to spindle synchronization mode while
rotating.
When the load inertia is larger, the setting value should be smaller.
When the setting value is larger, the orientation in-position and single-rotation position alignment
complete faster, but the impact applied on the machine will increase.
To change the deceleration rate only during rotation command (command F Δ T ≠ 0), set this
parameter together with SP070 (KDDT).
