Number Message Description
PS5305 ILLEGAL SPINDLE NUMBER For the spindle selection function using address P under multi
spindle control:
<1>Address P is not specified.
<2>The spindle selected with parameter No.3781 is not
specified.
<3>A G code that cannot be specified with S_P_; is specified.
<4>The multi spindle function is not enabled because the
parameter EMS (bit 1 of parameter No.3702) is set to 1.
Note
NOTE
1 This function is available as an option.
2 Even if the conditions to start the spindle speed fluctuation detection function are
satisfied, the spindle speed fluctuation detection function is not performed under
the following conditions:
・The specified spindle speed is 0 min
-1
.
・A search by program restart is in progress.
3 If the spindle stop signal *SSTP<Gn029#6> is set to 0, detection is not performed.
4 If any of the spindle stop signals *SSTP1 to *SSTP4<Gn027#3,#4,#5,Gn026#6> is
set to 0, detection is not performed on the corresponding spindle.
5 If alarm OH0704 is raised, a single-block stop occurs in automatic operation. The
spindle overheat alarm is displayed on the screen. In addition, the SPAL alarm
signal is output (the signal is set to 1 in the alarm state).
This signal is cleared to 0 by a reset.
6 If the cause of alarm OH0704 is not eliminated by a reset, the alarm will be raised
again.
7 Alarm OH0704 can be suppressed across an allowable variation width specified in
parameter No.4913. If the actual spindle speed continues to be 0 min
-1
for one
second or longer, however, an alarm will be raised.
8 The raising of alarm OH0704 does not automatically cause the spindle to stop.
8 G25 and G26 must be specified in a predetermined format. Avoid specifying the
preparatory function, auxiliary functions, and the like together with G25 or G26.
10 A serial spindle signal that can affect the actual spindle speed should be
manipulated in the G25 mode.
11 If a spindle is under velocity control, spindle speed fluctuation detection is carried
out.
12 Avoid making a spindle orientation operation while the spindle speed fluctuation
detection function is enabled.
13 If address P is used to select a spindle while the multi spindle function is carried
out, avoid specifying S_P_; together with G26. If this is attempted, alarm PS5305
will be raised.
