The axes are decelerated and stopped, then the program is interrupted. The remaining
axis movement commands can be continuously executed by turning the automatic start
(ST) input signal ON after returning to the automatic mode.
• M, S and T commands
These commands are processed depending on the setting for pm4009D7 (forced FIN
mode selection).
pm4009D7=0 (forced FIN mode set)
Both the sampling output (MFB to MFE) and the M code output are turned OFF,
and the M S and/or T command is assumed to have been completed. Therefore,
the interrupted M, S and/or T commands is not output even when an automatic
mode is recovered. SPL indicator is not lit.
pm4009D7=1 (forced FIN mode not set)
The M, S and/or T command is saved and the SPL indicator is lit.
3. If an automatic mode input signal or program edit mode input signal is given while an
axis is moved in a manual mode, the axis is decelerated and stopped.
4. An operation mode input is valid if only one of the input signals is “closed”. Under other
status conditions, the previously selected operation mode remains valid.
If there is no operation mode input signal or if more than one operation mode input signal
is given after the power is turned ON, the PCNC enters the manual jog feed mode.
