1.2.6 Relation Between Current Limit and Pressing Force
Perform the pressing operation with RCP2 (stepping motor).
Caution: (1)
The relation of the current limit and the pressing force is a reference
assuming when the speed is 20mm/s.
(2)
There will be a little variance in the actual pressing force. If the value of
current limit is small, the variance for the pressing force becomes big.
(3)
Use the product with the current limit within the range specified in the graph.
If used below 20%, the pressing force would not be stable. An operation may
not be made in some cases. An operation cannot be made also when it is
beyond 70%. If use in such a condition, it may extremely shorten the product
life by the degradation of insulator in the motor coil due to heat generation.
(4)
When the approaching speed (setting in the position table) to the pressing
start position is 20mm/s or less, the pressing operation will be made with the
approaching speed. In this case, also, the pressing force would not be
stable. In such cased, check in advance that the actuator can be used with
no problem before start using.
