IMPORTANT!

When the “program reset” is executed, the resetting output signal RST is maintained “closed” for

one second.

This output signal indicated that a part program is being rewound.

While a part program is rewound by the RWD input signal, in response to the M02 or
M30 command, the RWDS output signal remains “closed”.

Program Reset

The “program reset” is basically the same as the reset operation executed by pressing the
[RESET] soft-key on the PCNC Operation Panel or the reset operation executed in response to
the “closing” of the external reset [ERS] input signal. With the “program reset”, however, the
CNC memory rewind is not executed. For details of the reset operation, refer to “Safety and
Maintenance Functions” Section 2 of Chapter 10.
