8 OUTPUT MODULE
(6) Comment
(a) This device is used to create a comment such as purpose of roller axis.
Made comment can be displayed at monitoring using a peripheral device.
(b) Comments up to 32 characters long can be created.
POINT
(1) "Roller diameter" or "number of pulses per roller revolution" set in the roller
parameter is used for only the cycle speed monitor of servomotor, and it is not
related to the rotation speed/travel value of servomotor.
(2) The roller cycle speed monitor device is the same for the "feed current value"
in the real mode. Therefore, the position address (current value) of roller axis
cannot be monitored in the virtual mode.
When it switches from the virtual to real mode, the certain value is stored in
the position address (current value). The value at this time is an unfixed value.
