z
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.
Note: The home direction cannot be reversed for a rod-type actuator.
If the home direction is reversed, all position data that have been input will be cleared.
z
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
z
PIO jog speed
Define the speed at which the actuator will be jogged using PIO in the teaching mode.
The factory setting is “100 [mm/sec].”
Set an optimal value for the specific application.
z
Default speed
The factory setting is the rated speed of the actuator.
When a target position is written to an unregistered position table or the current position is read in the
teaching mode, 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.
z
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 or the current position is read in the
teaching mode, 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.
