Maximum Allowable Moment
Select the moment from within the range of
operating limits shown in the graphs. Note
that the maximum allowable load value
may sometimes be exceeded even within
the operating limits shown in the graphs.
Therefore, also check the allowable load
for the selected conditions.
Maximum Load Mass
Select the load mass from within the range
of limits shown in the graphs. Note that the
maximum allowable moment value may
sometimes be exceeded even within the
operating limits shown in the graphs.
Therefore, also check the allowable
moment for the selected conditions.
The graph value is for calculating the guide
load factors. Refer to the table below for
actual maximum load mass. The maximum
load mass shows the motor ability.
Refer to page 1099 for maximum load
mass value.
Caution
Select the required model by taking into
consideration the operating condition spec-
ifications and any possible specification
changes that may occur during operation.
Contact the nearest sales representative
for SMC's model selection software, which
will help in selecting the correct model.
Calculation of Guide Load Factor
1. Maximum allowable load (1), static moment (2), and dynamic moment (at the time of impact with
stopper) (3) must be examined for the selection calculations.
∗To evaluate, use υa (average speed) for (1) and (2), and υ(impact speed υ= 1.4 υa) for (3). Calculate m max
for (1) from the maximum load mass (m1, m2, m3) and Mmax for (2) and (3) from the maximum allowable moment
graph (M1, M2, M3).
Note 1) Moment caused by the load, etc., with actuator in resting condition.
Note 2) Moment caused by the impact load equivalent at the stroke end (at the time of collision to stopper).
Note
3) Depending on the shape of the workpiece, multiple moments may occur. When this happens, the sum of the
load factors (Σα) is the total of all such moments.

2. Reference formulas [Dynamic moment at impact]
Use the following formulas to calculate dynamic moment when taking stopper impact into considera-
tion.
m: Load mass (kg)
F: Load (N)
FE: Load equivalent to impact (at impact with stopper) (N)
a: Set acceleration (m/s2)
υ: Impact speed (mm/s)
M: Static moment (Nm)
L1: Distance to the load’s center of gravity (m)
ME:Dynamic moment (Nm)
FE= m a

∴ME= — FEL1(Nm)

Note 4) Average load coefficient (= ):
This coefficient is for averaging the maximum load
moment at the time of stopper impact according to
service life calculations.

Either the emergency
stop input is opened,
or the power supply
for the signal is cut-
off.
Confirm the power sup-

and release the emer-
gency stop input.
(Refer to the circuit dia-
gram on page 1106.)
External output is
short-circuited.
∗There is no external
alarm output signal.
In case of common
power supply, turn off
the power supply and
check the wiring condi-
tion of load. Restart the
power supply.
(Refer to the circuit dia-
gram on page 1106.)
The power supply
voltage is excessive
or lower than the limit
for operation.
Check the power sup-
ply voltage and adjust it
if necessary, then press
the MIDDLE button.
In case of an indepen-
dent power supply, turn
off the power supply for
the signals and check
the wiring condition of
load. Restart the power
supply.
(Refer to the circuit dia-
gram on page 1106.)

abnormality Maximum output is
continued for a pro-
longed period of time.
Check the work weight
and confirm that no for-
eign materials are at-
tached to the actuator.
After confirming, press
the MIDDLE button.
Temperature
abnormality Internal temperature
of the controller is
high.
Lower the surrounding
temperature of the ac-
tuator in use, and then
press the MIDDLE but-
ton.
Note) The product is in the same condition as when the stroke learning process is
completed.
Return to the home position is not performed by the initial input
• If the error can not be corrected, turn off the power supply to stop operation, and
contact your SMC sales representative.

Abnormal
stroke
The motor is revolving
at excessive speed or

achieved.
If any foreign materials
are observed, remove
them and then press

firm the connection of the
connector part between the

please confirm the con-
nector part between
the motor and the con-
troller after cutting off
the power supply.
The CPU is malfunc-
tioning or the mem-
ory content is abnor-
mal.
Turn off the power sup-
ply and restart it.
After turning off the power
supply, check to see
whether the stroke adjust-
ing unit is loose. If re-
quired, readjust the stroke
and perform the stroke
learning again. Note)
Reset the settings for
speed and acceleration
to the set values while

There are two types of alarm reset: alarm reset manually (a) and an alarm reset externally (b) by an external signal.
Alarm reset
a: Alarm reset manually
In the event of an alarm, simply pushing wwill revert from the alarm
state.
b: Alarm reset externally
In the event of an alarm, simply inputting an external emergency stop
signal for 50 ms or longer will return to the state prior to the alarm. The
emergency stop output will activate by releasing the input for the
emergency stop.
The followings are the reinstated condition.

When mounting an auto switch, first hold the switch spacer with your fingers and push it into the groove. Confirm that it is aligned evenly within the groove
and adjust the position if necessary. Then, insert the auto switch into the groove and slide it into the spacer.
After establishing the mounting position, use a watchmaker’s flat head screwdriver to tighten the switch mounting screw which is included.
Note) When tightening an auto switch mounting screw, use a watch-
maker’s screwdriver with a handle of approximately 5 to 6 mm in
diameter. Also, tighten with a torque of about 0.1 to 0.15 Nm.
As a guide, turn about 90°past the point at which tightening can
first be felt.
