Number Message Description
218
NOT FOUND P/Q COM-
MAND IN G251
The G51.2 block does not contain P or Q,
or a specified value is invalid.
The causes of this alarm are detailed in
DGN No. 471. (See below.)
DGN No. 471#7 NPQ
When P and Q are not specified at all, R
is specified. Alternatively, none of P, Q,
and R has been specified.
DGN No. 471#6 PQE
P or Q is out of the valid data range. Alter-
natively, P and Q are not specified as a
pair.
DGN No. 471#5
A negative value is specified at Q when
bit 1 (QDRC) of parameter No. 7603 = 1.
DGN No. 471#4 NSP
There is no spindle necessary for control.
(The spindle is not a serial spindle, or there
is not the second spindle, etc.)
219
COMMAND G250/G251 IN-
DEPENDENTLY
G51.2/G251 and G50.1/G250 are specified
together with other commands in the same
block. Correct the program.
221
ILLEGAL COMMAND IN
SYNCHRO
An attempt was made to perform polygon
synchronization operation together with Cs
contouring control or balance cutting. Alter-
natively the program issued a command for
spindle--spindle polygon synchronization
mode, when the spindle is under spindle
synchronization control, Cs contouring con-
trol, spindle positioning control, or rigid tap-
ping control, etc.
Correct the program.
5018
POLYGON SPINDLE SPEED
ERROR
The specified rotation ratio cannot be main-
tained during the G51.2 mode, because the
speed of the spindle or polygon synchro-
nization axis exceeds the clamping value or
is too low.
The causes of this alarm are detailed in
DGN No. 471. (See below.)
DGN No. 471#3 SUO
The specified speed is too high.
DGN No. 471#2 QCL
The polygon synchronization axis (se-
cond spindle) is clamped.
DGN No. 471#1 PCL
The master axis (first spindle) is
clamped.
DGN No. 471#0
The specified speed is too low.
(Remark)
In a properly connected machine, P/S alarm No. 5018 does not basically
occur for other than a reason that the polygon synchronization axis is
clamped. (See descriptions of DGN for details.)
