(3) Parameter setting for spindle drive unit
Starts the safe observation function.
【#13229】 SP229 SFNC9 Spindle function 9
bit F : ssc Safety observation function
0: Disable 1: Enable
bit D : rps Safety observation speed setting unit
0: Normal 1: 100°/min
The digital signal input selection is set to "1" for the drive unit connected with the door state signal. The
digital signal input selection is set to "0" for the other drive unit not connected with the signal.
【#13227】 SP227 SFNC7 Spindle function 7
bit F-C : dis Digital signal input selection
0: No signal 1: Safety observation function door state signal 4: Proximity switch signal detection
Other settings: setting prohibited
Sets the safety speed of the machine and motor for which the safety observation is executed.
【#13238】 SP238 SSCFEED Safety observation Safety speed
Set the safety speed at the spindle end for the safety observation function.
When not using, set to "0".
---Setting range---
0 to 18000 (゜/min)
However, when SP229/bitD is set to "1", the setting range is from -32768 to 32767 (100゜/min).
【#13239】 SP239 SSCRPM Safety observation Safety motor speed
Set the motor's safety speed for the safety observation function.
When not using, set to "0".
---Setting range---
0 to 32767 (r/min)
(Note) The value of the safety observation safety speed and safety observation safety motor speed
must satisfy the following relation.
If this relation is not satisfied, the parameter error (37or E4) will occur. (Error parameter No. is
239.)
Checking this relation is executed when the drive unit is turned ON and parameter is changed
and speed observation mode (states when a speed observation command is turned ON) is
entered.
Note that "1 (r/min)" is applied when the calculation result is "0 (r/min)"
