6.16.5 Precautions
(1) Designating deceleration check
•
When in-position check is valid, set the in-position width in the servo parameters.
(2) Deceleration check for opposite direction movement reversal
•
When deceleration check is valid (G0Ipfg=1), deceleration check will be executed when the
axis reverses its movement to the opposite direction at the G1
→
G0 successive block
regardless of whether G0 non-interpolation is ON or OFF.
•
When deceleration check is valid (G0Ipfg=1), deceleration check will be executed when the
axis reverses its movement to the opposite direction at the G1
→
G0 successive block even in
the fixed cycle.
•
In the G1
→
G28, G1
→
G29 or G1
→
30 successive blocks, deceleration check will always be
executed when the G1 movement is completed, when movement to the intermediate point is
completed and when movement to the return point is completed. Note that if the base
specification parameter simple zero point return (#1222 aux06/bit7) is valid, the base
specification parameter G1
→
G0 deceleration check (G0Ipfg) will be followed when the G1
movement is completed and when movement to the intermediate point is completed.
(Deceleration check will always be executed when movement to the return point is completed
even in this case.)
(3) Designating in-position width
•
When the in-position width (programmable in-position check width) is set in the machining
program with E68, either the in-position width set with the parameter (SV024, G0inps, G1inps)
or that set in the program, whichever larger, is applied when performing an in-position check.
•
When the SV024 setting value is larger than the G0 in-position width/G1 in-position width, the
in-position check is carried out with the SV024 value.
•
When error detect is ON, in-position check will be forcibly carried out.
(4) Deceleration check in G1
→
G0, G1
→
G1 opposite direction movement reversal during
high-speed machining mode
•
When the axis movement reverses to the opposite direction in a G1
→
G1 successive block
during the high-speed machining mode, the commanded deceleration will not take place even if
G1Ipfg is set to 1. Note that the G0Ipfg setting will be followed if the axis direction reverses to
the opposite direction in a G1
→
G0 successive block.
