5. Parameter Settings
5.2.2 Parameters Relating to the Actuator Operating Characteristics
Default speed (No. 8 VCMD)
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.
Default acceleration/deceleration (No. 9 ACMD)
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.
Default positioning band (in-position) (No. 10 INP)
The factory setting is “0.10 [mm].”
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 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.
Current-limiting value during home return (No. 13 ODPW)
A current value appropriate for the standard specification of the actuator has been set at the time of shipment.
Increasing the value set in this parameter increases the home return torque.
This parameter need not be changed in normal conditions, but in certain situations such as when the slide
resistance increases due to the affixing method, load condition, etc., of the actuator used vertically, the home
return may complete before the correct position. In this case, the value set in parameter No. 13 must be
increased.
(As a guide, the set value should not exceed 75%.)
Current-limiting value at standstill after positioning (No. 12 SPOW)
A current value appropriate for the standard specification of the actuator has been set at the time of shipment.
Increasing the value set in this parameter increases the holding torque at standstill.
This parameter need not be changed in normal conditions, but if a large external force is applied to the actuator at
standstill, hunting may occur. In this case, the value set in parameter No. 12 must be increased.
(As a guide, the set value should not exceed 70%.)
Speed override (No. 46 OVRD)
Use this parameter to move the actuator to prevent danger at the trial run startup time.
When a movement command is issued from the PLC, an override can be applied to the movement speed set in
the “Speed” field of the position table by the setting in parameter No. 46.
Actual movement speed = [Speed set in the position table]
[setting in parameter No. 46] 100
Example) Value in the “Speed” field of the position table: 500 (mm/s)
Setting in parameter No. 46: 20 (%)
In this case, the actual movement speed becomes 100 mm/s.
The minimum setting unit is 1% and the input range is 1 to 100 (%). The factory setting is 100%.
(Note) This parameter is invalid for the movement command by the PC or teaching pendant and the movement command by
direct numeric specification.
When the PC or teaching pendant is used, operation can be performed by setting a speed ratio on such a tool.
Caution: For the positioning band, set the value greater than that of the encoder resolution.
Setting it smaller may cause a servo error.
