Chapter 2 Input Axis Module
[Md.301] Servo input axis speed
The speed for the servo input axis is stored in servo input axis speed units (Refer to
Section 2.1.1).
The speed for the servo input axis is the value after processing smoothing, phase
compensation, and rotation direction restriction.
[Md.302] Servo input axis phase compensation amount
The phase compensation amount for a servo input axis is stored in servo input axis
position units (Refer to Section 2.1.1).
The phase compensation amount for a servo input axis is the value after processing
smoothing and phase compensation.
[Md.303] Servo input axis rotation direction restriction amount
While the rotation direction is restricted for a servo input axis, the accumulation for input
travel value in the opposite direction of the enabled direction is stored in servo input axis
position units (Refer to Section 2.1.1) as follows.
Setting value of "[Pr.304] Servo input
axis rotation direction restriction"
Storage details
1: Enable only for current value
increase direction
A negative accumulation is stored during rotation direction restriction.
0 is stored if there is no restriction.
2: Enable only for current value
decrease direction
A positive accumulation is stored during rotation direction restriction.
0 is stored if there is no restriction.
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.
