M01 OPERATION ERROR 

Alarms occurring due to incorrect operation by the operator 
during NC operation and those by machine trouble are 
displayed. 

Error No. 

Details 

Remedy 

DOG OVERRUN (Dog overrun) 

When returning to the reference point‚ 
the near-point detection limit switch did 
not stop over the dog‚ but overran the 
dog. 

•  Increase the length of the near-point 

dog. 

•  Reduce the reference point return 

speed. 

Z-AX NO CRSS  

One of the axes did not pass the 
Z-phase during the initial reference point 
return after the power was turned ON. 

•  Move the detector one rotation or more 

in the opposite direction of the reference 
point‚ and repeat reference point return.

INVALID RET (Invalid return)  

When manually returning to the 
reference point‚ the return direction 
differs from the axis movement direction 
selected with the AXIS SELECTION 
key. 

•  The selection of the AXIS SELECTION 

key’s +/– direction is incorrect. The error 
is canceled by feeding the axis in the 
correct direction. 

EXT INTRLK (External interlock)  

The external interlock function has 
activated (the input signal is "OFF") and 
one of the axes has entered the interlock 
state. 

•  As the interlock function has activated‚ 

release it before resuming operation. 

•  Check the sequence on the machine 

side. 

•  Check for broken wires in the interlock 

signal line. 

INTRL INTRLK (Internal interlock)  

The internal interlock state has been 
entered.  
The absolute position detector axis has 
been removed. 
A command for the manual/automatic 
simultaneous valid axis was issued from 
the automatic mode. 

•  The servo OFF function is valid‚ so 

release it first. 

•  An axis that can be removed has been 

issued‚ so perform the correct 
operations. 

•  The command is issued in the same 

direction as the direction where manual 
skip turned ON‚ so perform the correct 
operations. 

•  During the manual/automatic simul- 

taneous mode‚ the axis commanded in 
the automatic mode became the manual 
operation axis. Turn OFF the manual/ 
automatic valid signal for the 
commanded axis. 

•  Turn ON the power again‚ and perform 

absolute position initialization.
