G31 P99/98 cannot be used for axes subject to simplified synchronization
or the X–axis or Z–axis when under slanted axis control.
Bit 7 (SKF) of parameter No. 6200 must be set to disable dry run,
override, and auto acceleration or deceleration for G31 skip commands.
Do not use G31 P99/98 in consecutive blocks.
WARNING
Always specify a torque limit before a G31 P99/98
command. Otherwise, G31 P99/98 allows move
commands to be executed without causing a skip.
NOTE
If G31 is issued with tool nose radius compensation
specified, P/S alarm No. 035 is generated. Therefore,
before issuing G31, execute G40 to cancel tool nose radius
compensation.
