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-speed type
(Lead: 6 mm) (Lead: 8 mm)
High-speed type High-speed type
(Lead: 12 mm) (Lead: 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%.
