【#2118(PR) 】 S_DSI Speed monitor Door selection
Select which door group of the speed monitoring the spindle belongs to.
The belonging door group corresponds to the following bits of the parameter.
bit0 : Door 1
bit2 : Door 2
:
bitF : Door 16
It is possible to belong to two or more door groups.
(Example) 0013: Belongs to door 1, 2, and 5 groups.
The speed monitoring will not be executed when "#2313 SV113 SSF8/BitF" is OFF regardless of this
parameter.
The selected door group must be set when setting the synchronous control.
The spindle/C axis control enables the door selection in "#3071 SscDrSelSp" for the corresponding
spindle.
【#2140(PR)】 S_Fil Speed monitor Error detection time during servo OFF
Set the error detection time of command speed monitoring and feedback speed monitoring during
servo OFF.
An alarm will occur if the time, for which the speed has been exceeding the safe speed or safe
rotation speed, exceeds the error detection time set in this parameter.
If "0" is set, it will be handled as 200 (ms).
---Setting range---
0 to 9999 (ms)
【#2141】 chtL Chopping first-step time constant for soft acceleration and deceleration
Set the first-step time constant for the chopping axis when soft acceleration/deceleration is applied.
Note that, however, there may be cases where actual time constant is shorter than the set time
constant, because the time constant is automatically calculated according to the feedrate so that the
acceleration rate during acceleration/deceleration (clamp speed/chopping time constant) will be
constant.
When "0" is set, "#2007 G1tL" will be valid.

---Setting range---
0 to 4000 (ms)
【#2142】 cht1 Chopping second-step time constant for soft acceleration and deceleration
Set the second-step time constant for the chopping axis when soft acceleration/deceleration is
applied.
Note that, however, there may be cases where actual time constant is shorter than the set time
constant, because the time constant is automatically calculated so that the ratio between first-step
and second-step time constant will be constant.
When "0" is set, "#2008 G1t1" will be valid.
---Setting range---
0 to 4000 (ms)
Belongs to door 1 group when "0000" is set.
