PARAMETERS 
Description   xx  [ int ]  -    group number 
 nn  [ float ]  -    vector deceleration value 
 
Range  xx -   1 to MAX GROUPS 
 nn -  0 to minimum of the maximum deceleration values of all 
axes assigned to this group. 
 
Units  xx -  none 
 nn -    predefined units / second

Defaults   xx missing:  error 13, GROUP NUMBER MISSING 
  out of range:  error 14, GROUP NUMBER OUT OF RANGE 
  not assigned:  error 15, GROUP NUMBER NOT ASSIGNED 
 floating point: truncated 
 nn missing:   error 7, PARAMETER OUT OF RANGE 
  negative:   error 22, GROUP PARAMETER OUT OF RANGE 
  out of range:  error 25, GROUP MAXIMUM DECELERATION 
EXCEEDED 
 
DESCRIPTION  This command is used to set the vectorial deceleration value for a group.  This 
value will be used during coordinated motion of axes assigned to the group.  It 
will override any original deceleration values specified for individual axes using 
AG command.  The axes’ original values will be restored when the group to 
which they have been assigned is deleted. 
This command takes effect immediately.  It can be executed when controller is 
idling or motion is in progress or inside a program. 
Note: 
Avoid changing deceleration during acceleration or deceleration phases of a 
move.  For better predictable results, change deceleration only when all the axes 
assigned to this group are not in motion. 
 
RETURNS       If “?” sign takes the place of nn value, this command reports the current setting. 
 
REL. COMMANDS    AU  -    set maximum acceleration and deceleration for an axis 
  HN  -    create a new group 
  HA  -    set vectorial acceleration for a group
