A NC reset 1
[Function]
This signal is used to reset the control unit.
[Operation]
When this signal (NRST1) is turned ON, the control unit can be reset.
Generally, the signal of the reset button on the NC operation board is set to the "NC reset 1" (NRST1). At this time, the
control unit will be in the following states.
 The G command modal is held.
 The tool compensation data is held.
 The memory is indexed.
 The error/alarm is reset.
 The MST code output is held.
 The M code independent output (M00, M01, M02, M30) turns OFF.
 The axis movement stops.
 The "In reset" signal (RST) is output.
NC reset 1 (NRST1)
In reset (RST)
[Related signals]
(1) NC reset 2 (NRST2: YC19)
(2) Reset & rewind (RRW: YC1A)
(3) In "reset" (RST: XC15)
Cont. Signal name
A NC reset 2
[Function]
This signal is used to reset the control unit.
[Operation]
When this signal (NRST2) is turned ON, the control unit can be reset.
Generally, this is turned ON when the miscellaneous function M02 or M30 is executed. In some cases, the "Reset &

At this time, the control unit will be in the following states.
 The G command modal is initialized.
 The tool compensation data is canceled. (Will not be applied.)
 The memory is not indexed.
 The error/alarm is reset.
 The MST code output is held.
 The M code independent output (M00, M01, M02, M30) turns OFF.
 The axis movement stops.
 The "In reset" signal (RST) is output.
NC reset 2 (NRST2)
