4) Deceleration [G]…It is able to set the deceleration speed (G) at the stop.
(Reference) Explained here is about the acceleration speed. The way to think is the
same for deceleration.
1G = 9800mm/s 2 : Acceleration that enables to accelerate up to 9800mm/s in 1sec.
0.3G: Acceleration that enables to accelerate up to 9800mm/s
u 0.3 = 2940mm/s in 1sec.

5) Pressing Force [%] … It sets the pressing torque.
Increasing the current limitation value (%) increases the pressing
force.
When it is set to “0”, the positioning operation is not available.
Refer to the Catalog or the Instruction Manual for the correlation
between the pressing force and the current limitation value (%).
6) Pressing Width [mm]… It sets the distance for the pressing operation.
When a pressing operation is performed, the actuator drives with
the speed set in the positioning parameter and the rated torque as
it does for the normal positioning operation until the remained
movement amount reaches to the range that is set in the pressing
width parameter. After the actuator gets in the range, it starts the
pressing movement till it reaches to the position set in (1).
The speed during the pressing operation is 20mm/s (if the
parameter No.7 is remained the same as it is when delivered). Do
not set this value above 20mm/s. If the setting in (2) is lower than
the pressing speed, the pressing will be performed with the speed
set in (2).
Settings of Acceleration and Deceleration.
(1) Set the acceleration speed to a value that does not exceed the rated
acceleration/deceleration speed specified in the Catalog or this Instruction Manual. Use of
the actuator beyond the rated acceleration/deceleration speed may shorten the actuator
life remarkably.
(2) Lower the acceleration/deceleration setting in the case there is any impact or vibration
occurred on the actuator or the work part. Keeping the usage under such a condition may
shorten the actuator life remarkably.
(3) When the transported weight is obviously lighter than the rated transportable weight, the
acceleration speed could be set higher than the rated value. The takt time will possibly be
shortened by this. Please ask us in such a case. At that time, please inform us of the work
part weight, profile, attachment method and the condition of the actuator installation
(horizontal/vertical).
