is out of its valid range.
(3) n the G81 block, only one of P and Q is specified.
(4) In the G81.5 block, there is no command for the master or
slave axis.
(5) In the G81.5 block, data out of the specified range is
specified for the master or slave axis.

are each out of the range 2 to 4.
[Single Rotation Dwell]
The specified spindle rotation is “0” when single rotation dwell
is specified.
