6.20.5 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 and G1 -> G30 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's 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
- The in-position width (programmable in-position check width) designated in the machining program has a
priority over the in-position width set in the parameters (SV024, G0inps, G1inps).
- When error detect is ON, in-position check will be forcibly carried out.
(4) Deceleration check in G1 -> G0/G1 -> G1opposite 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.

width
Set the in-position detection width.
Set the accuracy required for the machine.
The lower the setting is, the higher the positioning accuracy
gets; however, the cycle time (setting time) becomes longer.
The standard setting value is "50".

# Items Details Setting range
2077 G0inps G0 in-position width
Set the in-position width for G0.
Between SV024 and this parameter, the parameter with a larger
value will be applied.
When "0" is set, this parameter will be invalid: only SV024 will
be available.
0.000 to 99.999 (mm)
2078 G1inps G1 in-position width
Set the in-position width for G1.
Between SV024 and this parameter, the parameter with a larger
value will be applied.
When "0" is set, this parameter will be invalid: only SV024 will
be available.
