(5) Push (Push)

 Select the positioning mode or push & hold mode.

The default value is “0.”
0:

Positioning mode (= Normal operation)

Other than 0: Push & hold mode [%]

 In the push & hold mode, enter the current-limiting value to be applied to

the servo motor while the load is being pushed. With the RCS, set the
current-limiting value to approx. 70%. The controller will not operate
properly if this value is 30% or below.

The table on page 33 lists the push force at standstill for each controller
type when the current-limiting value is set to 70%. Be sure to reference this
table to set an appropriate value for your controller.

Note: If the push force is too small, a false detection of push & hold

condition may occur due to slide resistance, etc., so exercise
caution.

(6) Positioning band

(Pos. band)

 The function of the positioning band varies depending on whether the

push & hold setting in (5) is “0” or “other than 0.”

[A] Push = 0 (Positioning mode)

 In the positioning mode, enter the position-complete detection width

(distance to the target position), in [mm].

 The distance to the target position indicates the range prior to the target

position, upon entry of the actuator in which range a position complete
signal will be output.
The default value is “0.1 [mm]” (Fig. A).

[B] Push = Other than 0 (Push & hold mode)

 Enter the maximum push amount (distance from the target) in the push &

hold mode, in [mm] (Fig. B).

 If the push direction corresponds to the negative direction along the

displayed coordinate axis, add a – (minus) sign to the entered value.
