The feed axis related with the spindle
The feed axis number related with the spindle should be set when matches with the CS axis
function.
Setting value meaning: 0: Without 1~5: the 1
st
axis ~ the 5
th
axis

MSEN
Bit4 1: The multiple spindle control function is valid;
0: The multiple spindle control function is invalid;

RCS RSCS
RCS =1: The spindle Cs function is valid;
=0: The spindle Cs function is invalid.
RSCS =1: The spindle contour control is disabled in emergency stop, reset;

MSEN SALM2
MSEN =1: The multiple spindle control function is valid;
=0: The multiple spindle control function is invalid.
SALM2 =1: The system alarms when the check input signal of the 2

spindle abnormality is
LOW;

spindle abnormality is
HIGH;
Function description(defined by the standard PLC program
）
1.1. After the multiple spindle control function setting is valid, the system defaults to the 1
st
spindle control after power-on;
1.2. When M03, M04, M05 is executed, the corresponding signal of the 1
st
spindle outputs, at
that time, the system sets the 1
st
spindle control, hereafter, the S command being executed
will change the 1
st
spindle speed. In a similar way, M63, M64, M65 is executed, the
corresponding signal of the 2
nd
spindle outputs, at the time, the corresponding signal of the
2
nd
spindle outputs, and is switched into the 2
nd
spindle control, after that, the executed S
command will change the 2
nd
spindle speed.
1.3. The spindle switch is invalid in rigid tapping.
1.4. The manual CW, CCW, STOP, SPINDLE OVRRRIDE keys on the panel are valid only to the
1
st
spindle. When the current system is controlled by the 2
nd
spindle, the manual control key
of the spindle on the panel still controls the 1
st
spindle.
1.5. The spindle override of the 2
nd
spindle is fixed to 100%.
1.6. Cs axis control of two spindles can be separately switched and the current used spindle has
no requirements, that is, when the current is the 1
st
(2
nd
) spindle, the 2
nd
(1
st
) spindle
executes the Cs switch.

Cs control logic of the 2
nd
spindle
1.1. After M24 is executed, PLC sets the spindle contour controllable signal CON (G127.7) to 1;
1.2. CNC controls the drive to shift the controllable method, after the shifting is performed,
CNC
→
PLC outputs the spindle contour controllable shifting end signal FSCSL (F144.1);
1.3. After the PLC detects the spindle contour controllable shifting end signal FSCSL (F144.1),
end the performance of the M24. The spindle controllable method is then completed.
2. M25 execute processes are the same those of M24.
3. M25 only cancels M24 executing the speed/position switch. Executing M25 cannot switch the
