5. Explanation of Operating Functions

5.1.1 Relationship of Push Force at Standstill and Current-Limiting Value

When performing operation in the push & hold mode, enter the current-limiting value (%) in the push column of

the position table.

Determine the current-limiting value (%) from the push force to be applied to the work part at standstill.

The graphs below illustrate the relationship of push force at standstill and current-limiting value for each actuator

type:

z Slider type

(1) SA6C type (2

) SA7C type

Low-speed type Low-speed type

(Lead: 3 mm) (Lead:

4 mm)

Medium-speed type Medium-spee

d type

(Lead: 6 mm) (Lead: 8 mm)

High-speed type High-spee

d type

(Lead: 12 mm) (L

ead: 16 mm)

Caution: The precision of push force at standstill is not guaranteed. The above graphs are provided for

reference purposes only. If the push force is too small, malfunction may occur during push &

hold operation due to slide resistance, etc., so exercise caution.

The maximum current-limiting value is shown in the above graphs. The minimum value is 20%.
