Correlation Graph for Pressing Force / Current Limit Value
Current Limit Value [%]
Pressing Force [N]
Caution: (1) The relation of the current limit value and the pressing force is a reference
when assuming the speed is 20mm/s.
(2) There is 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%. 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.
