=0: External cycle start signal (ST) is valid;
Bit 5 =1: External stop signal (SP) is invalid;
=0: External stop signal (ST) is valid; the external feed hold switch is needed,
otherwise, “Feed hold” is displayed.
z External connection circuit
The external connection circuit of SP, ST signals is shown in Fig. 2-49:

z Function description (defined by standard PLC program)
M09 is active, i.e. M08 is inactive, after CNC power on. To execute M08, M08 output is active and
cooling is turned on; to execute M09, M08 output is cancelled and cooling is turned off.
Note 1: M08 output is cancelled at CNC emergency stop.
Note 2: Whether M08 is cancelled is set by BIT3 of the bit parameter No.009 when CNC is reset.
When Bit1=0, M08 output is cancelled as CNC is reset;
When Bit1=1, M08 output is not cancelled as CNC is reset;
Note 3: There is no corresponding output signal for M09, and M08 output is cancelled if M09 is executed.
Note 4: The cooling can be controlled by the key on operation panel, see details in OPERATION.
