17.5 TORQUE LIMIT SKIP
If a move command is specified after G31 P99 (or G33 P98) when the
servo motor torque limit(*1) is overridden, the same cutting feed as that
achieved by linear interpolation (G01) is possible. If the servo motor
torque reaches the torque limit (overridden servo motor torque limit)
due to pressing, or if a skip signal (or high-speed skip signal) is entered
during movement according to this move command, the remaining part
of the move command is cancelled, and the next block is executed.
*1 : The servo motor torque limit corresponding to the setting of a
motor type is automatically set.

G31: Skip command (one-shot G code)
P98: A skip operation is performed when the servo motor
torque reaches the torque limit.
P99: A skip operation is performed when the torque of the
servo motor reaches the torque limit or if a skip signal is
entered.
Q: Torque limit override value
Specifiable range: 1 to 99 (%)
The Q command can be omitted. When omitting the Q
command, however, specify a torque limit in the PMC
window beforehand. When the Q command is omitted, a
PS alarm (PS0151) is issued if a torque limit override is
not set beforehand.
If a value that is not within the specifiable range is
specified, a PS alarm (PS0150) is output.
A specified override value is valid only in the block in
which the override value is specified. At the end of the
skip operation, the override value returns to the value
being used immediately before G31 was specified.
α: Axis address of an arbitrary axis
F: Feedrate
Skip operation is performed in following conditions
