S1 : for First spindle / S2 : for Second spindle / S3 : for Third spindle
This parameter sets the serial spindle motor speed at which the motor
speed detection signal is output. The speeds of the serial spindle motors
for the first, second, and third spindles are monitored, and the motor speed
detection signal, indicating whether the speed of each spindle exceeds the
value set in this parameter, is output to the Y address specified with
parameter No.1891.
NOTE
1 The motor speed detection signals are not output when the
servo/spindle motor speed detection function is not used, or
0 is set for this parameter.
2 For this parameter, set a motor speed rather than a spindle
speed.

before operation is continued.
[Data type] Bit
ND1 In controlling the spindle synchronization, the direction of the first
spindle motor rotation is:
0 : The direction indicated by the command sign
1 : The opposite direction to that indicated by the command sign
ND2 In controlling the spindle synchronization, the direction of the 2nd
spindle motor rotation is:
0 : The direction indicated by the command sign
1 : The opposite direction to that indicated by the command sign
ND3 Under synchronous spindle control, the direction of rotation of the third
spindle motor is:
0 : The same as the specified sign.
1 : The opposite of the specified sign.
This parameter is usable only when
parameter SSS (bit 4 of parameter No. 3704) = 1.
ND4 Under synchronous spindle control, the direction of rotation of the fourth
spindle motor is:
0 : The same as the specified sign.
1 : The opposite of the specified sign.
This parameter is usable only when
parameter SSS (bit 4 of parameter No. 3704) = 1.
