ALARM Off : Normal
On : Alarm state (Communication with the CNC is stopped.)
The operator’s panel connection unit (source output type) has a function
for issuing an alarm upon detecting an excessive current that may flow
through the output driver element as a result of such as DO grounding.
If an alarm state is detected, the CNC is placed in the system alarm state,
and the LED corresponding to the DO causing that alarm is turned on.
(See the table below.)
By using setting pin CP1 on the board, the CNC can be prevented from
being placed in the system alarm state due to an output driver alarm.
DAL1 Off : Normal
On : An error occurred in DO output Yq+0.0 to Yq+0.7.
DAL2 Off : Normal
On : An error occurred in DO output Yq+1.0 to Yq+1.7.
DAL3 Off : Normal
On : An error occurred in DO output Yq+2.0 to Yq+2.7.
DAL4 Off : Normal
On : An error occurred in DO output Yq+3.0 to Yq+3.7.
DAL5 Off : Normal
On : An error occurred in DO output Yq+4.0 to Yq+4.7.
DAL6 Off : Normal
On : An error occurred in DO output Yq+5.0 to Yq+5.7.
DAL7 Off : Normal
On : An error occurred in DO output Yq+6.0 to Yq+6.7.
DAL8 Off : Normal
On : An error occurred in DO output Yq+7.0 to Yq+7.7.
A system alarm caused by one of the above alarms is indicated as follows:
“SLC ERROR aa(bb)” Example: “SLC ERROR 03(01)”
(aa: XXXXXX11 Bits 0 and 1 are set to 1. The other bits are
undefined.)
(bb: XXXXXXX1 Bit 0 is set to 1. The other bits are undefined.)
Setting of setting pin CP1
Open : An alarm is reported to the CNC.
Connected : No alarm is reported to the CNC.
