AXIS : Axis to command
XBF-PN04B:1~4, XBF-PN08B:1~8
VEL_FACTOR : Override ratio for speed
(or Command speed)
ACC_FACTOR :
Override ratio for acceleration time
(or Command acceleration time)
DEC_FACTOR :
Override ratio for deceleration time
(or Command deceleration time)
S_RATIO : Unused
(S-curve ratio (0= Trapezoid, 1~100: S-curve ratio))
DIRECTION : Operating direction
(1 ~ 3: 1-forword, 2-reverse, 3-current)
Output
DONE : Maintain 1 after first operating
STAT : Output the error no. in operation
(1)
Give “Acceleration/deceleration speed override” command to the axis designated as the axis of positioning
module with BASE (Base no. of Positioning module) and SLOT (Slot no. of Positioning module).
(2) This command is used when the command axis is in operation and you want to change operation speed,
acceleration, deceleration, direction.
(3) VEL_FACTOR, ACC_FACTOR, DEC_FACTOR is
configurable
in “speed override” of common parameters, it can be set “%” or “speed(unit/time)”.
(4) If the unit of the speed override is set the speed percent(%), it means ratio for acceleration time override
ratio and configurable setting area is -65,535 ~ +65,535. It means actually -655.35% ~ 655.35%. If you set a
negative value, it will operate in the opposite direction.
(5) If the unit of the speed override is set the speed value, configurable setting area is -
(‘speed limit’ of
‘operation parameter’) ~ +(‘speed limit’ of ‘operation parameter’). The units of the speed override value
follow the axis unit.
(6) If the unit of the acceleration override is set the percent (%),it means ratio for acceleration time override ratio
and configurable setting area is -65,535 ~ +65,535. It means actually -655.35% ~ 655.35%.
(7) If the override value unit of acceleration/ deceleration is a speed value, configurable setting area is
0~ 4,294,967,295.
