The CNC is reset and enters the reset state in the following cases:
1. When the emergency stop signal (*ESP) is set to 0
2. When the external reset signal (ERS) is set to 1
3. When the reset and rewind signal (RRW) is set to 1
4. When MDI RESET key is pressed
When the CNC is reset, the resetting signal (RST) is output to the PMC.
The resetting signal (RST) is set to 0 when the resetting signal output
time, set with parameter No. 3017, has elapsed after the above conditions
have been released.
RST signal output time = T
reset
(Reset processing time) + (parameter
setting value) 16 msec.

16 msec
CAUTION
T
reset
requires at least 16 msec. This time will be longer on
optional configurations.
When the CNC is reset during automatic operation, automatic operation
is stopped and tool movement along the controlled axis is decelerated and
stopped(*1). When the CNC is reset during the execution of the M, S, T,
or B function, signal MF, SF, TF, or BF is set to 0 within 100 ms.
Tool movement along the controlled axis is also decelerated and
stopped(*1) in manual operation (jog feed, manual handle feed,
incremental feed, or etc).
CAUTION
*1 When the emergency stop signal (*ESP) is set to 0, the tool
is stopped by an emergency stop.
Bit 6 (CLR) of parameter No. 3402 is used to select whether the CNC
internal data (such as modal G codes) is cleared or reset when the CNC
is reset. Refer to the Appendix E, ”Status when turning on power, when
cleared, and when reset” in the Operator’s manual for the state of the
internal data when cleared or reset.
