13.2 Torque limit skip
General
Sepcifying a move instruction after G31 P99 (or G31 P98) with a motor torque limit
set (for example, specifying a torque limit on the PMC screen) allows the same
cutting feed as that specified with G01 to be performed. While the tool is moved with
a motor torque limit set during cutting feed, skip is performed when a signal
indicating that the motor torque limit has been reached is input as a result of an
operation such as pushing somethind agaist the motor.
Basic operations When the motor torque limit is reached or the SKIP signal <X002#4> is input
during the execution of G31 P99, the execution of the next block starts without
executing the remaining portion of the move instruction. When the motor
torque limit is reached during the execution of G31 P98, the execution of the
next block starts without executing the remaining portion of the move
instruction. When no torque limit is specified before executing G31 P99 or P98,
the move instruction is executed without performing the skip operation. For
G31 P99 and P98, the coordinate, indicating the position to which the tool is to
be positioned after skip, is stored during the system variable of the custom
macro.

[Classfication] Output signal
[Function] Reports that the torque limit has been reached.
[Output conditions] Set to “1” when :
·The torque limit has been reached for the corresponding axis.
Set to “0” when:
·The torque limit has not been reached for the corresponding axis.
Number 1 to 4 report the corresponding axis numbers.
Signal address
Note:
1. Specify a torque limit before G31 P99/P98. If G31 P99/P98 is executed with no
torque limit specified, the move instruction is executed without a skip operation.
2. When G31 P99 is specified, the SKIP signal causes a skip operation. However,
avoid using the high-speed skip operation.
3. Before specifying G31 P99/P98, cancel tool-tip radius compensation with G40.
4. Set the SKF bit(bit 7 of parameter No.6200) to 0 to disable the dry run, override,
and automatic acceleration/deceleration functions for the G31 skip instruction.
