32 Setting the Deceleration Check
571 IB-1501268-K
32.6 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. Confirm the DEN (motion command completion) signal with
PLC before the execution of the MSTB command which needs to be executed after the completion of the axis
movement.
(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 "1" is set for "#1205 G0bdcc" (Acceleration and deceleration before G0 interpolation), the in-position width
will be the value of "#2224 SV024" (In-position detection width). "#2077 G0inps" (G0 in-position width) and ",I
command" programmable in-position check will be invalid.
(7) When the machine is locked and in pre-interpolation acceleration/deceleration, the control axis is always in the in-
position state. (The in-position signal of each axis stays ON.)
(8) During synchronous operation, in-position check method 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 at the G1 -> G0 successive block regardless of whether G0
non-interpolation is ON or OFF.
- When deceleration check is valid (#1502 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 -> 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 completed. (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.
(Note 1) When G1 command is issued, the in-position check is performed regardless of the deceleration
check parameter.
(Note 2) XX expresses all commands.
