4 Setup
#2336 SV136 RPn0L
Set this parameter to operate distance-coded reference check when using distance-coded reference scale.
During the distance-coded reference check initial setup (SV137:RAER=-1), set the following items on the NC
drive monitor screen after the distance-coded reference check initial setup warning A3 turns OFF.
SV134=Rn, SV135=Pn, SV136=MPOS
When reference point is set, the warning A3 turns OFF.
To enable the distance-coded reference check function, SV081/bit3=1setting and a battery option are need-
ed.
Related parameters: SV081/bit3,7, SV130, SV131, SV134 to SV137
---Setting range---
-32768 to 32767
#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)
