[Md.303] Servo input axis rotation direction restriction amount
While the rotation direction is restricted for a servo input axis, the accumulation for input movement amount in the opposite
direction of the enabled direction is stored in servo input axis position units (Page 29 Servo input axis position units) as
follows.
Setting value of "[Pr.304] Servo input axis rotation direction
restriction"
1: Enable only for current value increase direction
2: Enable only for current value decrease direction
Rotation direction restriction is processed after phase compensation processing. Therefore, if undershoot occurs from phase
compensation during deceleration stop, the rotation direction restriction amount might remain.

Storage details
A negative accumulation is stored during rotation direction restriction.
0 is stored if there is no restriction.
A positive accumulation is stored during rotation direction restriction.
0 is stored if there is no restriction.
