The following parameters are also used to select how to handle
processing for CNC data when the CNC is reset.
S Bit 7 (MCL) of parameter No. 3203
Whether programs created in MDI mode are erased or stored
S Bit 6 (CCV) of parameter No. 6001
Whether custom macro variables #100 to #149 are cleared or stored
S Bit 7 (CLV) of parameter No. 6001
Whether custom macro local variables #1 to #33 are cleared or
stored
When the reset & rewind signal (RRW) is set to 1, reset is performed and
the following rewinding operation is also performed.
1. When the DNC operation mode, and a portable tape reader is
connected as the current input/output device, the tape reader is
rewound.
While the tape reader is being rewound, the rewinding–in–progress
signal (RWD) is output. This signal goes 0 when the tape reader has
been rewound.
2. In cases other than case 1, the head of the selected main program is
searched for. Setting RWM, bit 2 of parameter no. 3001, determines
whether the rewinding–in–progress signal is output.
When RWM is set to 1:
The rewinding–in–progress signal is output. It is set to 1, then set to
0 after about 100 ms. Since searching for the main program in memory
takes little time, when the rewinding–in–progress signal (RWD) is set
to 0, the main program has already been searched for.
[Classification] Input signal
[Function] Reset the CNC.
[Operation] Turning the signal ERS to 1 resets the CNC and enters the reset state.
While the CNC is reset, the resetting signal RST turns to 1.
[Classification] Input signal
[Function] CNC is reset and a program under an automatic operation is rewound.
[Operation] As described in the item, “Reset & Rewind”.
