Caution: (1) The relation of the current limit and the pressing force is a reference when
assuming the speed is 20mm/s.
(2) There will be a little variance in the actual pressing force.The variance of the
pressing force becomes large when the current limit value is low.
(3) Use the product within the range in the graph for the current limit value. Pressing
force will not be stable if used below 20% (below 30% for Lead 16). There is even
a case that it would not operate. An operation cannot be made also when it is
beyond 70%. Doing so may cause degradation in the motor coil insulation by
heat radiation, which results in shortening the product life.
(4) When the approach speed to the pressing start position (setting in the position
table) is 20mm/s or less, pressing will be performed with the approach speed. In
such a case also the pressing force will be unstable. In such cases, check in
advance that the actuator can be used with no problem before omit using.
