Specifications Note 2) Note 1) Please consult with SMC for non-standard strokes as they are produced as special orders. Note 2) Do not allow collisions at either end of the table traveling distance at a speed exceeding “pushing return to origin speed.” Additionally, when running the positioning operation, do not set within 2 mm of both ends. Note 3) A reference value for correcting an error in reciprocal operation. Note 4) Maximum acceleration/deceleration changes according to the work load. Refer to the “Work Load.Acceleration/Deceleration Graph (Guide)” for ball screw drive on pages 7 and 8. Note 5) Each value is a guide. Use such value to select a motor capacity.
