15. PMC CONTROL FUNCTION
B–64113EN–1/01
1012
[Classification] Input signal
[Function] When an auxiliary function command (EC0g to EC6g: 12h) is issued by
the PMC, the auxiliary function code is specified in a byte (using signals
EID0g to EID7g) or two bytes (using signals EID0g to EID15g),
depending on the setting of bit 6 (AUX) of parameter No. 8001.
The CNC sends the auxiliary function code specified in signals EID0g to
EID7g and EID8g to EID15g to auxiliary function code signals EM11g
to EM28g and EM31g to EM48g and awaits the auxiliary function
completion signal EFINg. When the auxiliary function completion signal
EFINg is returned, the CNC starts executing the next block.
The timings for sending the auxiliary function code signals and auxiliary
function strobe signal, as well as for receiving the auxiliary function
completion signal, are the same as those for the miscellaneous functions
(M functions) under the control of the CNC. See “Auxiliary function
executing signal” for details.
[Classification] Input signal
[Function] When this signal is set to “1”, the servo motor for the corresponding
PMC–controlled axis is turned off (servo–off state).
When this signal is set to “0”, the servo motor is turned on.
When a torque control command (EC0g to EC6g: 11h) is specified,
entering the servo–off state cancels torque control mode, but the torque
control state remains set. In such a case, set reset signal ECLRg to “1”.
[Classification] Input signal
[Function] When this signal is set to “1”, commands from the PMC are not read while
the executing, waiting, or input buffer contains a block. If this signal is
set to “1” when any of these buffers contain a block, that block is executed
but subsequent commands are read only when the buffers are all empty.
To discriminate the buffering disabled condition, the CNC outputs the
axis control command read completion signal (EBSYg) only when a
command is read when all buffers are empty.
