5 PARAMETERS FOR POSITIONING CONTROL
(1) Stroke limit range check
The stroke limit range is checked at the following start or during operation.
Operation start Check Remarks
• Positioning control
(PTP, Constant-speed)
• It is checked whether the positioning address is within
the stroke limit range or not at the positioning start. If it
outside the range, an error occurs (error code: 580) and
positioning is not executed.
• If the interpolation path exceeds the stroke limit range
during circular interpolation start, an error occurs (error
codes: 207, 208) and deceleration stop is executed.
• JOG operation
• When the current value is executed a deceleration stop
from current command speed, if the current value
exceeds the stroke limit range, a deceleration stop is
made before a stroke limit. (Error code: 207) Travel to
the direction that returns the axis into the stroke range
is possible.
• Manual pulse generator
operation
Check
• If the current value exceeds the stroke limit range, it
stops at stroke limit. (Error code: 207) In this case, a
deceleration stop is not made. Travel to the direction
that returns the axis into the stroke range is possible.
POINTS
(1) Besides setting the upper/lower stroke limit value in the fixed parameters, the
stroke limit range can also be set by using the external limit signals (FLS, RLS).
(2) Positioning from outside the stroke limit range cannot be executed. After
returning the axis to within the stroke limit range by the JOG operation or
manual pulse generator operation, execute the positioning control.
