Note 2) The maximum workload at 3000 m/s .
Speed varies according to the work load. Check the "Speed–Work Load
Graph" as a Guide in the catalogue on the SMC website
(URL: https://www.smcworld.com).

Furthermore, if the cable length exceeds 5 m, then the speed and work
load may decrease by up to 10% for each additional 5 m.
Note 3) A reference value for correcting an error in reciprocal operation.
Note 4) Impact resistance: No malfunction occurred when the actuator was tested
with a drop tester in both an axial and a perpendicular direction to the lead
screw. The test was performed with the actuator in the initialized state.
Vibration resistance: No malfunction occurred in a test ranging between
45 to 2000 Hz. The test was performed in both an axial and a perpendicular
direction to the lead screw. The test was performed with the actuator in the
initialized state.
Note 5) The power consumption including the controller is for when the actuator is
operating.
Note 6) For models with lock only.
Note 7) For an actuator with lock, add the power consumption for the lock.

3.1 Installation
(Step motor 24 VDC)
Battery-less absolute
• Do not install the product unless the safety instructions have been read
24 VDC ±10%
and understood.
222 • Do not use the product in excess of its allowable specification.
• When installing, inspecting or performing maintenance on the product,
Non magnetizing lock
be sure to turn off the power supplies. Then, lock it so it cannot be
75 113 245
tampered with while work is happening.

• Keep the flatness of the mounting surface to within 0.1 mm maximum.
24 VDC ±10%
Insufficient flatness of a work piece or actuator mounting surface can
cause play in the guide and increased sliding resistance. In the case
of overhang mounting (including cantilever), use a support plate or
support guide to avoid deflection of the actuator body.
• When mounting the actuator, use all mounting holes.
If all mounting holes are not used, this will not maintain the specified
performance. e.g. the amount of displacement of the table will increase.
• When mounting the actuator leave a gap of 40 mm or more to allow
for bending of the actuator cable.
• When mounting the actuator or workpiece, use screws with adequate
length and tighten them with adequate torque.
Tightening the screws with a torque higher than recommended may
cause malfunction, whilst tightening with a torque lower than
recommended can cause displacement of the mounting position, or
dropping of the work piece.
