6.16 Deceleration Check
6.16.1 Functions
The purpose of the deceleration check is to reduce the machine shock that occurs when the control axis
feedrate is suddenly changed, and prevent corner roundness. The check is carried out at block joints.

(1) Deceleration check during rapid traverse
The deceleration check is always carried out at the block joints during rapid traverse, before executing
the next block.
the next block.
(2) Deceleration check during cutting feed
The deceleration check is carried out at the block joints (before executing the next block) during cutting
feed when any one of the following conditions is valid.
feed when any one of the following conditions is valid.
1) When the error detect switch is ON.
2) When G09 (exact stop check) is commanded in the same block.
3) When G61 (exact stop check mode) has been selected.

Designating
deceleration
check
The deceleration check by designating a parameter includes “deceleration check specification type 1”
and “deceleration check specification type 2”. The setting is selected with the parameter “#1306
InpsTyp”.
and “deceleration check specification type 2”. The setting is selected with the parameter “#1306
InpsTyp”.
(a) Deceleration check specification type 1 (“#1306 InpsTyp” = 0)
The G0 and G1 deceleration check method can be selected with the base specification parameter
deceleration check method 1 (#1193 inpos) and “deceleration check method 2” (#1223 aux07/bit1).
deceleration check method 1 (#1193 inpos) and “deceleration check method 2” (#1223 aux07/bit1).
