abnormality alarm.
Note 1: In the emergency stop, it turns off M03, M04, M08 signals, and outputs M05 signal;
Note 2: Whether M03, M04 is cancelled is set by BIT3 of the bit parameter No.009 when CNC is
reset.
If Bit 1=0, CNC turns off M03, M04 at reset;
If Bit 1=1, M03, M04 is kept at reset.
2.8.5 Spindle switching volume control
� Relevant signal(defined by standard PLC program)
S01～S04: Control signal for spindle speed switching volume, they are compound
interfaces
defined by standard PLC program, and they share common interfaces with M41～M44,
U00～U03.
� Signal diagnosis
Signal S4 S3 S2 S1
Diagnosis address Y1.3 Y1.2 Y1.1 Y1.0
Interface pin CN62.12 CN62.11 CN62.10 CN62.09
� Control parameters
Bit parameter
0 0 1 ACS
Bit4 =1: Analog voltage control of spindle speed
=0: Switching volume control of spindle speed

Ⅲ Connection
S1～S4 output are inactive at power on. If any code of them is executed, the
corresponding S
signal output is active and held on, and the other S signal outputs are cancelled. S1～S4
outputs are
cancelled when executing S00 code, and only one of them is active at a time.
2.8.6 Spindle automatic gearing control
� Relevant signal (defined by standard PLC program)
M41～M44: spindle automatic gear shifting output signals. It supports 4-gear spindle
automatic
gear shifting control when the system selects the spindle analog value control(0～
10V analog voltage output)
M41I,M42I: spindle automatic gear shifting No.1, 2 gear in-position signals to support gear
shifting in-position check function
� Signal diagnosis
Signal M42I M41I M44 M43 M42 M41
Diagnosis address X1.6 X1.5 Y1.3 Y1.2 Y1.1 Y1.0
Interface pin CN61.15 CN61.14 CN62.12 CN62.11 CN62.10 CN62.09
� Signal connection
