2. FUNCTION SPECIFICATIONS THAT DIFFER
FROM THE M series
(a) Nibbling mode
When the *SP signal is set to 0 during positioning to the first punch
point in nibbling mode, positioning stops. This sets the STL signal to
0 and the SPL signal to 1, such that the system enters the feed hold
Also, when the *SP signal is set to 0 during pitch movement from the
first punch point to the last punch point, the system enters the feed hold
state. The system can enter the feed hold state after a pitch movement
which sets the *SP signal to 0 provided the NSP bit (bit 2 of parameter
16181) is set accordingly. If this setting is made, press start signal PF
and nibbling signal NBL are set to 0 when press stop signal *PE is set
(b)Workpiece holder escape mode
If the *SP signal is set to 0 in escape mode, the system stops after the
escape is completed.
Even in the machine lock state, the press function and external operation
function can be executed. So, miscellaneous function lock signal AFL,
T–command ignore signal TNG, and press start lock signal PFL should
all be set to 1 and external operation function selection signal EFS to 0
in the machine lock state.

[Data type] Bit
PRC When the machine lock signal, MLK, is set to 1, a program check is:
0 : Not executed.
1 : Executed.
The machine position data is updated although the actual position is not
changed. This setting is invalid for the machine lock signal of each axis.
