14.19.2 Function Enabling Conditions

The following settings are required to enable this function.
(1) Set "1" in "#1471 mgralmstp (Enable machine groupwise alarm stop)".
(2) Set the machine group number as follows.
[Servo axis]
 Set the machine group number of each axis in "#1605 mgrnum (Machine group No.)".
 When the machine group number is set to "0", the axes will decelerate and stop even if an alarm occurs in any machine
group.
[Spindle]
 There are two types of setting methods to set the machine group number as a single or multiple machine groups. The
types can be switched by "#3195 mgrsptyp (Spindle's machine group setting type)".
0 : Set single machine group number
1 : Set multiple machine group number
 When "0" is set in "#3195 mgrsptyp (Spindle's machine group type)" , set the machine group number in "#3196 mgrsp-
num1 (Spindle's machine group No. 1)".
When "0" is set in "#3196 mgrspnum1 (Spindle's machine group No. 1)", the spindle decelerates and stops even if an
alarm occurs in any machine group.
 When "1" is set in "#3195 mgrsptyp (Spindle's machine group type)", set the machine group number in "#3197 mgrsp-
num2 (Spindle's machine group No. 2)".
When "00" is set in "#3197 mgrspnum2 (Spindle's machine group No. 2)", the spindle continues the operation even if an
alarm occurs in any machine group. If you want to make the spindles to decelerate and stop for all machine groups, set
"FF" in "#3197 mgrspnum2 (Spindle's machine group type)".
(3) The group settings of the machine group number become effective when the power is turned OFF and ON again after
entering the parameter values.
(4) When all axes are set to the same machine group, the function is invalid.
