3)  P1-4 for G31, or Q1-4 for G04 was commanded without a 

multistage skip function option. 

4)  <T series > The specified value of address P of G72 or G74 

falls outside the range.    Address P ranges from 1 to 4 in the 
multistage skip function.    P1-4 was specified in G72 or G74 
even though the multistage skip function option is not 
present.

ILLEGAL FORMAT IN G10 OR L50 

In a command format for a programmable parameter input, an 
attempt was made to change the parameter for an encryption 
(No. 3220), key (No. 3221), or protection range (No.3222 or 
No.3223) as a "the encryption function for the key and program." 
Modify the program.   

0372 REFERENCE 

RETURN 

INCOMPLETE 

An attempt was made to perform an automatic return to the 
reference position on the orthogonal axis before the completion 
of a return to the reference position on the angular axis. 
However, this attempt failed because a manual return to the 
reference position during angular axis control or an automatic 
return to the reference position after power-up was not 
commanded. First, return to the reference position on the 
angular axis, then return to the reference position on the 
orthogonal axis. 

0373 

ILLEGAL HIGH-SPEED SKIP SIGNAL

In the skip commands (G31, G31P1 to G31P4) and dwell 
commands (G04, G04Q1 to G04Q4), the same high-speed 
signal is selected in different paths. 

0374 

ILLEGAL REGISTRATION OF TOOL 
MANAGER(G10) 

G10L75 or G10L76 data was registered during the following 
data registration: 
- From the PMC window. 
- From the FOCAS2. 
- By G10L75 or G10L76 in another system. 
Command G10L75 or G10L76 again after the above operation 
is completed. 

0375 

CAN NOT ANGULAR 
CONTROL(SYNC:MIX:OVL) 

Angular axis control is disabled for this axis configuration. 
1)  When some related axes under angular axis control are not 

in synchronous control mode or when one angular axis is not 
paired with the other angular axis or one Cartesian axis is 
not paired with the other Cartesian axis in synchronous 
control 

2)  When some related axes under composite control are not in 

composite control mode or when one angular axis is not 
paired with the other angular axis or one Cartesian axis is 
not paired with the other Cartesian axis in composite control 

3)  When related axes under angular axis control is switched to 

superposition control mode1)

SERIAL DCL: ILLEGAL PARAMETER

1.  When Parameter No.1815#1 is set to “1”, parameter 

No.2002#3 is set to “0” 

2.  The absolute-position detection function is enabled. 

(Parameter No.1815#5 is set to “1”. ) 

0387 

ILLEGAL RTM DI/DO VAR 

There is no DI/DO variable that has a specified signal address 
(alphabet, number).
