29.6 Precautions
(1) When in-position check is valid, set the servo in-position width of the servo parameter.
(2) This function is invalid for the axes in the automatic machine lock.
(3) When the MSTB is commanded to the next block of the cutting commanded block, the MSTB code is output before the
completion of the cutting command deceleration. The MSTB command must be executed after axis movement is com-
plete. To execute the MSTB command, first confirm the DEN (motion command completion) signal with a PLC, and then
execute.
(4) When the control axis in the synchronous/superimposition control exists in the part system for which in-position check
method has been set, the deceleration completion will be determined when the smoothing for all axes reaches zero.
(Same as the smoothing check method)
(5) When the thread cutting commands are issued consecutively, the deceleration check will not be performed at the block
joint.
(6) When the parameter "#1205 G0bdcc"is set to "1", the value of in-position width set by "#2224 SV024" (In-position detec-
tion width) is applied.
In this case, in-position width setting of the parameter "#2077 G0inps" (G0 in-position width) and in-position check will be
invalid.
(7) When pre-interpolation acceleration/deceleration is valid by the high accuracy control command etc. during the machine
lock operation, the "Each axis in-position" signal is always turned ON.
(8) During synchronous operation, the "Each axis in-position" signal cannot be used.
(9) Deceleration Check for Opposite Direction Movement Reversal
When deceleration check is valid ("#1502 G0Ipfg" = "1"), deceleration check will be executed when the axis reverses its
movement to the opposite direction in a G1 to G0 successive block regardless of whether G0 non-interpolation is ON or
OFF.
When deceleration check is valid ("#1502 G0Ipfg" = "1"), deceleration check will also be executed when the axis
reverses its movement to the opposite direction in a G1 to G0 successive block in fixed cycles.
In the G1 -> G28, G1 -> G29 or 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 simple zero point return "#1222 aux06/bit7" is valid, G1 -> G0 deceleration check
(#1502) will be followed when the G1 movement is completed and when movement to the intermediate point is com-
pleted. (Deceleration check will always be executed when movement to the return point is completed even in this case.)
(10)Deceleration check in movement including spindle/C-axis
The deceleration check for spindle/C-axis movement command is as described in the table below. That is because a
vibration and so on occurs in the machine when the position loop gain (#13002 PGN) is changed during the axis
movement.
When G1 command is issued, the in-position check is performed regardless of the deceleration check parameter.
