[Data type] Bit
CVR When velocity control ready signal VRDY is set ON before position
control ready signal PRDY comes ON
0: A servo alarm is generated.
1: A servo alarm is not generated.
OZR When manual reference position return is attempted in the halt state
during automatic operation (feed hold stop state) under any of the
conditions listed below:
0: Manual reference position return is not performed, with P/S alarm
No.091.
1: Manual reference position return is performed without an alarm
occurring.
< Conditions >
(1) When there is a remaining distance to travel.
(2) When an auxiliary function (miscellaneous function, spindle–speed
function, tool function) is being executed.
(3) When a cycle such as a dwell cycle or canned cycle is being executed.
FFR Feed–forward control is enabled for
0 : Cutting feed only
1 : Cutting feed and rapid traverse
RBK Backlash compensation applied separately for cutting feed and rapid
traverse
0: Not performed
1: Performed
TRC The servo trace functon is:
0 : Disabled
1 : Enabled (Also set parameter No.1870.)
The digital servo software for learning control is necessary.
