Note 1: If selecting “N” for controller, also select “N” for I/O cable length.
Note 2: Use PLC unit which satisfies the ECPT pulse string signal input specifications (refer to
pages 5 to 13 in “SM-612271 Controller Instruction Manual”).
Note 3: If the controller is E or F, these cables can be used only when the differential system is
used as the pulse string signal system.
Only the 2 m cable can be used for the open collector system.

Note 2: For information on the operation speed range, refer to “SM-612271 Controller (EC07/EC63/ECPT) Instruction Manual”.
Note 3: When the speed is increased, the maximum load capacity is decreased. Refer to "1.4.2 Correlation between the speed and the
load capacity".
The horizontal load capacity values of the ESD2 Series are the values when used with an external guide.
Note 4: Use a power with sufficient capacity for the instantaneous maximum current.

1.4.2 Correlation between the speed and the load capacity
ERL2 Series (slider type)
•The operation speed is set by a value determined by the screw lead.
•Since the vertical load capacity depends on the speed, select the motor size and the screw
lead carefully.
•When transferring a workpiece, do not apply any shock to the slider, such as hitting it against
an external mechanical stopper.
•The set speed may not be reached depending on the stroke and the acceleration.

•Since the vertical load capacity depends on the speed, select the motor size and the screw
lead carefully.
•Use a system such as a linear guide with the product to prevent the piston rod from being
subjected to a lateral load or a rotational force.
•The values (load capacity) in the graphs below depend on the external conditions such as the
connection method and the friction resistance of the linear guide.
•When transferring a workpiece, do not apply any shock to the rod, such as hitting it against an
external mechanical stopper.
•The set speed may not be reached depending on the stroke and the acceleration.
•The horizontal load capacity values are the values when used with an external guide.

1.4.3 Correlation between the pressing force and the pressing current
setting value
The correlations between the pressing force and the pressing current setting value shown in the
graphs below are for reference only. Since the values (pressing force) depend on the conditions
of use, check the actual pressing force in accordance with the conditions.
