(※1) The motor component is not included in the measurement.
(※2) Please refer to the selection reference(correlation diagram of pressing force and electrical current limit value) in catalogue P.6 for pressing force.
(※3) The value is of when it operates in rated speed of 0.2G(Lead 5 will be 0.1G). The value shown as the horizontal load capacity here, is a value whenever the outer equipped guides are used along.
Following the characteristics of the pulse motor, the load capacity falls whenever the speed rises. Please refer to the correlation diagram of speed and load capacity in the P.6 of the catalogue for further information. ※ Please refer to the catalogue(PDF/1.5MB) for further information.
