Oadl (Optimal Acceleration)
[Function]
Automatically sets the optimum acceleration/deceleration according to the robot hand's load state (Optimum
acceleration/deceleration control).
By employing this function, it becomes possible to shorten the robot's motion time (tact).
The acceleration/deceleration speed during optimum acceleration/deceleration can be calculated using the
following equation:
Acceleration/deceleration speed (sec) = Optimum acceleration/deceleration speed (sec) x Accel instruction
(%) x M_SetAdl (%)
* The optimum acceleration/deceleration speed is the optimum acceleration/deceleration speed calculated
when an Oadl instruction is used.

9 Oadl Off
*When parameter HNDHOLD1 is set to 0, 1
[Explanation]
(1) The robot moves with the optimum acceleration/deceleration according to the hand conditions and work-
piece conditions designated with the LoadSet command.
(2) The workpiece grasp/not grasp for when the hand is opened or closed is set with parameter HNDHOLD
1 to 8.
(3) Initial setting of Oadl can be changed by the ACCMODE parameter. (Refer to
Movement parameter"
(4) Once Oadl is On, it is valid until Oadl Off is executed or until the program End is executed.
(5) Depending on the conditions of the hand and/or workpiece, the motion time may become longer than
usual.
(6) It is possible to perform the optimum acceleration/deceleration operation by using the LoadSet and Oadl
instructions, and by setting the HNDDAT1(0) through 8 and WRKDAT1(0) through 8 parameters to
appropriate values. (Refer to
deceleration settings)")
ON: Start the optimum acceleration/deceleration speed.
OFF: End the optimum acceleration/deceleration speed.
