1. AXIS CONTROL

WARNING
1 Compensation value range
Compensation values can be set within the range from –7
x compensation magnification (detection unit) to +7 x
compensation magnification (detection unit). The
compensation magnification can be set for each axis within
the range from 0 to 100 in parameter 3623.
2 Pitch error compensation of the rotary axis
For the rotating axis, the interval between the pitch error
compensation positions shall be set to one per integer of the
amount of movement (normally 360°) per rotation. The sum
of all pitch error compensation amounts per rotation must be
made to 0. Also, set the same compensation value to a
position and the same position with one rotation.
3 Conditions where pitch error compensation is not
performed
Note that the pitch error is not compensated in the following
cases:
· When the machine is not returned to the reference
position after turning on the power. This excludes the
case where an absolute position detector is employed.
· If the interval between the pitch error compensation
positions is 0.
· If the compensation position Nos. on the positive or
negative direction do not fall within the range of 0 to
1023.
· If the compensation position Nos. do not conform to the
following relationship:
Negative side x Reference position < Positive side
