Caution: (1) The relation of the current limit and the pressing force is a reference when
assuming the speed is 10mm/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 60%. Doing so may cause degradation in the motor coil insulation
by heat radiation, which results in shortening the product life.
(4) For CON-system controllers such as PCON, when the approach speed to
the pressing start position (setting in the position table) is 10mm/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.
For SEL-system controllers, such as MSEL, press at the speed set by
PAPR instruction, regardless of the approach speed up to the pressing
start position.
