13.2 Diagnosis Information (DGN) List
780
QCL : The second spindle (slave axis in polygon synchronization) is
clamped.
SUO : The speed specified in spindle polygon synchronization is too
high. (The speed is restricted to the upper limit for internal
operations.)
NSP : A spindle required for control is not connected. (The serial
spindle, second spindle, etc. is not connected.)
#5 : A negative Q value is specified while the PRM7603#1 (QDRC)
is set to 1.
PQE : The P value or Q value, specified with G51.2, falls outside the
predetermined range. Alternatively, the P and Q values are not
specified as a pair.
NPQ : Although the P and Q values are not specified with G51.2, an R
value is specified. Alternatively, none of the P, Q, or R value is
specified.
474
Rotation ratio of the master axis in spindle polygon synchroniza-
tion (specified P value)
DGN
In spindle polygon synchronization mode, the rotation ratio (specified P
value) of the current master axis (first spindle) is displayed.
475
Rotation ratio of the slave axis in spindle polygon synchronization
(specified Q value)
DGN
In spindle polygon synchronization mode, the rotation ratio (specified Q
value) of the current slave axis (second axis) is displayed.
476
Phase difference between two spindles in spindle polygon syn-
chronization (specified R value)
DGN
In spindle polygon synchronization mode, the current phase difference
(specified R value) is displayed.(The units are the minimum input increment
for the rotation axis of the machine.)
If the PRM7603#5 (RDGN) is set to 1, the shift amount specified for the serial
spindle (number of specified pulses, calculated at a rate of 4096 pulses per
360 degrees) is displayed.
477
Actual speed of the master axis for spindle polygon synchroniza-
tion (min
–1
)
DGN
In spindle polygon synchronization mode, the actual speed of the master
axis (first spindle) is displayed.
478
Actual speed of the slave axis in spindle polygon synchronization
(min
–1
)
DGN
In spindle polygon synchronization mode, the actual speed of the slave axis
(second spindle) is displayed.
