Appendix
Caution: [1] Even if you issue a position command or high-value command with specified S-motion
acceleration/deceleration in order to change moving speed while the actuator is operating,
trapezoid control, rather than S-motion acceleration/deceleration control, is performed.
Make sure to issue a command when the actuator is stopped.
[2] S-motion acceleration/deceleration is disabled in the index mode of the rotary actuator.
Trapezoid control is performed even if S-motion acceleration/deceleration control is specified.
[3] If acceleration or deceleration time exceeding 2 seconds is set, do not command S-motion
acceleration/deceleration control. Normal operation cannot be performed.
[4] Do not suspend the operation during acceleration or deceleration. The speed changes
(accelerates), which may be dangerous.
 Load-output judgment time
Parameter No. 50 (Load output judgment time) is not used with this controller.
 Ball screw lead
Parameter No. 77 defines the ball screw lead.
The controller is shipped from the factory with an optimal value set in this parameter according to the
characteristics of the applicable actuator.
* Do not change the setting.
