Allowable deviation error ratio
(Maximum speed pulse ratio)

138

1 ~ 9999

Deviation is compared against “Steady-state deviation of
maximum operating speed of each axis + Pulse speed of
maximum operating speed of each axis x Allowable
deviation error ratio.”

65

Mating synchro-axis number

0

0 ~ 8

Must be input for both axes. (Of the axis pair, the axis with
the smaller axis number becomes the master axis. Both
axes must have the same resolution characteristics.
Commands cannot be issued to the slave axis.)
(Invalid if “0” is set)
* The synchronization function cannot be used.

66

Mode selection for rotational
movement axis

0

0 ~ 5

0: Normal, 1: Index mode

67

Short-cut control selection
for rotational movement axis

0

0 ~ 5

0: Do not select, 1: Select (Valid only in the index mode

AND when an incremental encoder is used)

68

Mode selection for linear
movement axis

0

0 ~ 5

0: Normal, 1: Infinite-stroke mode (Note: Positioning

boundary applies. This setting can be specified only when
an incremental encoder is used.)

1: P32 is read automatically even when P33 = 0. P33 = 0

indicates “actual distance.”

P21 = Offset travel at home return
P12 = Coordinate achieved by offset travel at home return

0.001 mm Maximum lift command amount before brake unlock (Input

with sign)
(Suppression of momentary drop upon servo ON when a
heavy object is placed)
* Important: Input using the same sign as the rising

coordinate direction. (0.100 mm to 0.500 mm in absolute
value as a guideline)

* The servo-ON check time (axis-specific parameter No. 30)

must also be extended (approx. 1000 to 1500 msec) to
provide a sufficient time for rise-direction torque to follow.

(Valid only when installation of brake is specified.)
