#2337 SV137 RAER
For the distance-coded reference check function when using distance-coded reference scale, set the allow-
able gap from the reference point position data calculated by the main side encoder. When the gap exceeds
the allowable range, reference point created by distance-code is judged as wrong and detects alarm 42.
The standard setting value is "basic reference mark interval (SV130) / 4".
SV137=0 setting carries out the same operation as the standard setting value.
SV137=-1 setting enables the distance-coded reference initial set up mode and displays setting values of
SV134 to SV136 on NC drive monitor.
To enable the distance-coded reference check function, SV081/bit3=1setting and a battery option are need-
ed.
When SV137=32767, the distance-coded reference check function is disabled.
Related parameters: SV081/bit3,7, SV130, SV131, SV134 to SV136
---Setting range---
-1 to 32767 (mm)
#2338-2397 SV138 - SV197
Not used. Set to "0".
#2398 SV198 NSE
Set the special detection width for the no signal 2 (alarm 21).
This detects no signal 2 (alarm 21) when machine side feedback is not invoked even if the motor side encod-
er feedback exceeds this setting in the rectangular wave signal output linear scale.
When "0" is set, the detection will be performed with a 15μm width.
---Setting range---
0 to 32767 (μm)
#2399 SV199 RTGM
In case that machine resonance is induced when mounting a workpiece, the speed loop gain is switched au-
tomatically in response to inertia by setting the speed loop gain and workpiece inertia multiplier in advance.
The speed loop gain SV199(RTGM) changes in response to the estimated inertia ratio SV200(RTJX) based
on the speed loop gain SV005(VGN1) and the inertia multiplier SV037(JL) which were adjusted when no
workpiece was mounted.
When SV199 is set to "0", the adaptation of the speed loop gain will be disabled.
