- 662 -
NOTE
1 SCU becomes 1 also when the specified spindle
speed is 0 (DGN 470#7 = 1). In this case, however,
alarm PS5018 is not issued (because the command
is 0). When DGN 470#7 = 0 and DGN 471#0 = 1,
alarm PS5018 occurs. Normally this does not occur
with speed at which the spindle can rotate.
QCL The polygon synchronization axis is clamped.
NOTE
QCL becomes 1, when the polygon synchronization
axis receives a command with a polygon
synchronization speed that is higher than the value
specified in parameter No. 7621 and is clamped at
that speed.
SUO The specified speed is too high during the spindle-spindle polygon
synchronization mode.
(It is clamped to the upper limit calculated internally.)
NOTE
SUO occurs, if a result of (speed specified for the
master spindle)/(value specified at P) is higher than
59998. In other words, the master spindle must
rotate at a speed lower than 59998 min
-1
assuming
P = 1.
#4 Causes for alarm PS0314
When alarm PS0314 occurs, the polygon synchronization mode is
released, but the indication of its causes remains until the alarm
PS0314 is cleared by a reset.
NSP A spindle necessary for control is not connected.
(For example, there is not a serial spindle or the second spindle.)
The axis settings for polygon turning are not correct.
#5 to #7 Causes for alarm PS0218
When alarm PS0218 occurs, the polygon synchronization mode is
released, but the indication of its causes remains until the alarm
PS0218 is cleared by a reset.
QMS When bit 1 (QDR) of parameter No. 7603 = 1, a negative value is
specified at Q.
PQE In a G51.2, either P or Q has a value out of the specifiable range.
Or, P and Q are not specified as a pair.
