 Home return direction
Unless specified by the user, the home return direction is set to the motor direction at the factory.
Should a need arise to change the home direction after the actuator has been assembled into your system,
reverse the setting in parameter No. 5 between “0” and “1.”
Also change the home return offset, if necessary.
If necessary, also change the parameters for home return offset, soft limits and excited-phase signal detection
direction.
Note: If the home direction is reversed, all position data that have been input will be cleared.
 Home return offset
The controller is shipped from the factory with an optimal value set in parameter No. 22, so the distance from
each mechanical end to the home becomes uniform.
The minimum setting unit is “0.01 [mm].”
The home return offset can be adjusted in the following conditions:
[1] Want to align the actuator home and the system’s mechanical home after the actuator has been assembled
into the system
[2] Want to set a new home after reversing the factory-set home direction
[3] Want to eliminate a slight deviation generated after replacing the actuator
Note: If the home return offset has been changed, the soft limit parameters must also be adjusted
accordingly.
8.3.2 Parameters Relating to the Actuator Operating Characteristics
 Default speed
The factory setting is the rated speed of the actuator.
When a target position is written to an unregistered position table, the setting in this parameter will be used as
the speed data for the applicable position number.
To reduce the default speed from the rated speed, change the setting in parameter No. 8.
 Default acceleration/deceleration
The factory setting is the rated acceleration/deceleration of the actuator.
When a target position is written to an unregistered position table, the setting in this parameter will be used as
the acceleration/deceleration data for the applicable position number.
To reduce the default acceleration/deceleration from the rated acceleration/deceleration, change the setting in
parameter No. 9.
Type Lead Initial value
3 mm, 4 mm 0.2G
Slider
6 mm or more 0.3G
Rod 0.2G
 Default positioning band (in-position)
The factory setting is “0.10 [mm].”
When a target position is written to an unregistered position table, the setting in this parameter will be used as
the positioning band data for the applicable position number.
Increasing the default positioning band will allow the position complete signal to be output early. Change the
setting in parameter No. 10, as necessary.
