32 Setting the Deceleration Check
32.1 Function
The next block is executed after the axis is decelerated and stopped at the joint between the axis movement blocks. This
is to reduce the machine shock and to prevent the corner roundness, at the time when the sudden change of the control
axis feedrate occurs.
(1) Deceleration check during rapid traverse
The deceleration check is always carried out at the block end (before executing the next block) during rapid
traverse.
(2) Deceleration check during cutting feed
The deceleration check is carried out at the block end (before executing the next block) during cutting feed when
any one of the following conditions is valid.
(a) When the error detect switch is ON.
(b) When G09 (exact stop check) is commanded in the same block.
(c)
When G61 (exact stop check mode) has been selected.
(3) Selection of deceleration check method
There are three methods for the deceleration check: command deceleration check method, smoothing check
method and in-position check method.
The deceleration check method can be set independently for each execution block with the rapid traverse command
(G00) or the cutting feed command (G01/G02/G03).
(a) Operation list
This table shows the operation list for each movement command set.

◯ : Deceleration check is valid
( ◯ ) : (1)The deceleration check is valid when the error detect signal is ON, or G09 or G61 is valid.
(2) When the block commands G01 -> G00 are executed, #1502 G0Ipfg is turned ON, and the opposite
direction movement is reversed, the command deceleration check is performed.
(3) When the block commands G01 -> G01 are executed, #1503 G1Ipfg is turned ON, and the opposite
direction movement is reversed, the command deceleration check is performed.
In the case other than the above conditions, the deceleration check is not performed.
Refer to "Deceleration Check for Opposite Direction Movement Reversal" for the details of opposite
direction movement reversal.
×: Deceleration check is invalid
