The force judgment margin is be expressed with the base that the pressing current limit when
the force sensor is used is considered as 100%
(Note 1)
. It should be set in Parameters No. 95
and No. 96. The judgment range of the pressing complete should be determined as follows;
Pressing Setting [%] + Force Judgment Margin Positive [%] to
Pressing Setting [%] - Force Judgment Margin Negative [%]
Note 1 A value that the pressing current limit when the force sensor is used is considered
as 100% (force judgment margin)

RCP6-RRA7R-LCT
[Example of Setting]
Assuming the setting with RCP6-RRA6R-LCT at 500N, force judgment margin positive side at
5% and the force judgment margin negative side at 5%;
Pressing Setting ... 500 [N]
Force Judgment Margin Positive and Negative ... 1,000 [N] × 5% = 50 [N]
Therefore the judgment range of the pressing complete should be from 450 to 550 [N].
[How to Adjust]
It is recommended to check the status of the pressing force in pressing operation. Connect to
the PC software and read the current load with the servo monitor features
(Note 2)
to check.
If there is an overshoot or a step to the pressing force (current load) as shown in the figures
below, the phenomenon can be eased by adjusting in the following process.
