[9] Input/Output signal

Function
Whenever FSP input is on, clamp output [1],[2],[3],[4],[5],[6],[7],[8] turned on
one by one. However, when [ Program mode > Clamp output > number of
effective clamp (FN) ] is set to 1, FSP input is ineffective.
Whenever FSM input is on, clamp output [8],[7],[6],[5],[4],[3],[2],[1] turned off
one by one. However, when [ Program mode > Clamp output > number of
effective clamp (FN) ] is set to 1, FSM input is ineffective.
Whenever FP1 input is on, clamp output [1],[2],[3],[4] turned on one by one.
Whenever FM1 input is on, clamp output [4],[3],[2],[1] turned off one by one.
However [ Program mode> clamp output block division number setting (OFB)]
is set to no or set to 4, or [ number of valid clamp setting (F21N)] is set to 1,
FM1 input is ineffective.
Whenever FP2 input is on, clamp output [5],[6],[7],[8] turned on one by one.
Whenever FM2 input is on, clamp output [8],[7],[6],[5] turned off one by one.
However [ Program mode> clamp output block division number setting (OFB)]
is set to no or set to 4, or [ number of valid clamp setting (F22N)] is set to 1,
FM2 input is ineffective.
If IFR signal is on, all clamp outputs are turned off.
Whenever A2F input is on, following operation (1), (2), (3) is repeated.
This signal is effective when [Program mode > Setting for Pneumatic two-step
clamp(AF2)] is on.
When IF1 input is on, OF1 output is turned on.
When IF1 input is on again, OF1 output is turned off.
(same from IF2 toIF8）
When F1C input is on, OF1 output is prohibited.
（same from F2C to F8C）
When WC input is on, W output is prohibited.
When TC input is on, Thread trimmer sequence output T, L and W is
prohibited.
When S6 input is on while machine is driving, the machine is stopped and
when S6 input is off, the machine start driving again.
When S6 input is on while thread trimming operation, machine is stopped
after trimming.
When HPC is ON, home returning operation by the home positioning key or
HP signal is prohibited.
When setting of [ Program mode > Thread breakage sensor on/off ] is on, the
signal can be used for thread breakage detection input.
displayed. (Returns by power supply re-turning on)
When IO0 input is on, OT0 output is turned on at the same time.
(same from IO1 to IOF)
Anything does not operate, if NO input is turned on.
When SRT input is on, sewing operation is started. However, when clamp
output is turned off, this signal is invalid.
However, please note there is a timing that becomes invalid, for example
while machine is running.
When PF input is on, The presser foot will return to home position.
When PF input is on again, presser foot goes to down position.
When JGP input is on, XY table is moved in positive direction according to
the pattern.
When JGP input is on, XY table is moved in negative direction according to
the pattern.
When STP input is on, machine is stopped.
Specifications
(1)When A2F input is on first time, AFL output is turned on.
(2)When A2F input is on second time, AFH output is turned on.
(3) When A2F input is on third time, AFE output is turned on.
