14.19.4 Operation after Machine Group-Based Alarm Stop

Operations of another machine groups after machine groupwise alarm stop
 The allowance of the automatic operation by the cycle start can be switched.
 Whether to operate automatically by the cycle start is set by "#1472 mgralmrestart (Allowing automatic operation to start
after machine groupwise alarm stop)".
- 0 : Not allow automatic operation to start after machine groupwise alarm stop
- 1 : Allow automatic operation to start after machine groupwise alarm stop
 When "#1472 mgralmrestart (Allowing automatic operation to start after machine groupwise alarm stop)" is set to "0", an
operation error (M01 0137) occurs if you execute the automatic operation by the cycle start.
The manual operation for the axes of another machine groupsafter machine groupwise alarm stop (Avail-
able regardless of the parameter)
 When an alarm occurs at each machine group in the circumstance that the multiple machine group
numbers are set in optical channels:
[Axis parameter]
#
1022(PR) axname2
1605(PR) mgrnum
[Spindle parameter]
#
3195(PR) mgrsptyp Spindle's machine group setting type
3196(PR) mgrspnum1
3197(PR) mgrspnum2
When an alarm occurs at Z1 axis, the axes/spindles which belong to the machine group 1 perform the alarm stop. However,
the other axes/spindles/PLC axes are able to continue the operation without the alarm stop.
