Chapter 3 Before positioning
3- 48
Remark
ā¢ With M code signal On, if you execute the next operation step number, error code 233 will
come out and the operation will not happen.
Therefore, for positioning of the next operation step number with M code signal āOn,ā you
must reset M code signal as M code Off instruction (MOF).
(7) Acceleration/Deceleration Numbers
ā¢ Sets the Acc./Dec. numbers to be used in the step during the acceleration/deceleration time set in
the basic positioning parameter.
ā¢ The setting range is 1~4.
ā¢ For details about the acceleration/deceleration time, see 3.2.3.
(8) Operation Speed
ā¢ Set the target speed at which to operate in the step.
ā¢ The setting range is 1 ~ 100,000 pulse (unit:1pps).
ā¢ The operation speed should be set higher than or equal to the bias speed set in the basic
positioning parameter, and lower than or equal to the speed limit.
(9) Dwell Time
ā¢ The dwell time to be applied to the operation step.
ā¢ The dwell time refers to the time needed to maintain the precise stop of the servo motor in
controlling the positioning by using the servo motor, and also the standby time given before the next
positioning operation when one positioning operation is finished.
ā¢ Especially when the servo motor is used, it might not reach the target position or stay excessive
even though the output of the positioning function has been stopped, so the dwell time is the data
that set the standby time until the stable rest.
ā¢ The operation status of the axis of the XGB positioning function during the dwell time maintains
āOperation,ā and if the dwell time passes, the operation status signaling bit (axis X:
K4200(%KX6720), axis Y: K4300(%KX6880)) turns Off and the positioning completion signal turns
On.
