5.2 RESET AND REWIND
General
- RESET
The CNC is reset and enters the reset state in the following cases:
1. When the emergency stop signal (*ESP) is set to 0 by setting bit 0
(ENR) of parameter No. 2001
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
Upon a reset, the reset in-progress signal (RST) is set to 1. The reset
in-progress signal (RST) remains set to 1 for at least one second or until
conditions 1 through 4 above are cleared.
By setting bit 0 (RSD) of parameter No. 2000, the reset in-progress
signal is handled so that the signal is set to 1 when only condition 4 is
set to 1. It is set to 0 when all the reset conditions are cleared.
If a reset occurs during automatic operation, that automatic operation is
stopped. Signals MF, SF, TF, and BF are all set to 0. Movement along
controlled axes is decelerated and stopped. (An emergency stop is
applied when the emergency stop signal (*ESP) is set to 0.)
By using the parameters listed in the table below, the user can choose
whether to clear the CNC internal data (such as modal G codes) upon a
reset. For details of such data, see the description of each function.
