If <NEXT option> is added, the robot proceeds to the next no-movement
instruction without waiting for movement to finish. However, the following
instructions are not executed until robot movement ends (pass start).
Robot motion instructions (CHANGETOOL, CHANGEWORK, SPEED,
JSPEED, ACCEL, JACCEL, DECEL, JDECEL), optimal carrying mass setting
library (aspACLD, aspChange), arm movement library (mvSetPulseWidth, etc.)
If this command is used with a movement option, the NEXT option is no longer
valid. When <NEXT option> is added and if step stop is executed in the
waiting status for the next movement instruction, the robot will stop after the
movement ends. Therefore care needs to be exercised since it requires a long
distance to stop.
Remarks:
The APPROACH statement can be rewritten using the MOVE statement.
APPROACH <Interpolation method>,[<Pass start displacement> ]<Base
position>,<Approach length> [,<Motion option>][,NEXT]
The following shows the statement if the above APPROACH statement is
rewritten using MOVE.
6-axis MOVE <Interpolation method>,[<Pass start displacement> ]<Base
position>+(0, 0, -<Approach length>)H[,<Motion option>][,NEXT]
Example : APPROACH P, P3, 100
'The same as MOVE P, P3+(0, 0, -100)H.
4-axis MOVE <Interpolation method>,[<Pass start displacement> ]<Base
position>+(0, 0, <Approach length>)[,<Motion option>][,NEXT]
Example : APPROACH P, P3, 100
'The same as MOVE P, P3+(0, 0, 100).
