 Default acceleration/deceleration mode
This value is treated as the data in the “Acceleration/deceleration mode” field corresponding to the applicable
position number when a target position has been written to the unregistered position table.
The factory setting is “0 [Trapezoid].
To change the default acceleration/deceleration pattern, set an applicable value in parameter No. 52 as shown
below.
Setting
Trapezoid pattern 0
S-motion 1
Primary delay filter 2
 Current-limiting value during home return
The factory setting conforms to the standard specification of the actuator.
Increasing this setting will increase the home return torque.
This setting need not be changed in normal conditions of use. However, if an increased slide resistance causes
the home return to complete before the correct position depending on the affixing method, load condition or other
factor when the actuator is used in a vertical application, the value set in parameter No. 13 must be increased.
Please contact IAI.
 Speed override
Use this parameter when moving the actuator at a slower speed to prevent danger when the system is initially
started for test operation.
When move commands are issued from the PLC, the moving speed set in the “Speed” field of the position table
can be overridden by the value set by parameter No. 46.
Actual moving speed = [Speed set in the position table] x [Value of parameter No. 46]
 100
Example) Value in the “Speed” field of the position table 500 (mm/s)
Value of parameter No. 46 20 (%)
Under the above settings, the actual moving speed becomes 100 mm/s.
The minimum setting unit is “1 [%],” while the input range is “1 to 100 [%].” The factory setting is “100 [%].”
(Note) This parameter is ignored for move commands from the PC and teaching pendant.
 Safety speed
This parameter defines the feed speed to be applied during manual operation.
The factory setting is “100 [mm/sec].”
To change this speed, set an optimal value in parameter No. 35.
Take note that the maximum speed is limited to “250 [mm/s]” and that you should set a speed not exceeding this
value.
