- When 3-dimensional cutter compensation is specified, the 

modal state is illegal. 

- When the table coordinate system is set as the programming 

coordinate system, table rotate and 3-dimensional cutter 
compensation are specified after the start of tool center point 
control. 

- There is a difference in type1/type 2 specification between 

3-dimensional cutter compensation and tool center point

Description 

SV0001 

SYNC ALIGNMENT ERROR 

In feed axis synchronization control, the amount of 
compensation for synchronization exceeded the parameter 
(No. 8325) setting value. 
This alarm occurs only for a slave axis. 

SV0002 

SYNC EXCESS ERROR ALARM 2 

In feed axis synchronization control, the amount of 
synchronization error exceeded the parameter (No. 8332) 
setting value. When the synchronization is not completed 
after power-up, the determination is made by the parameter 
value (No. 8332) multiplied by the parameter (No. 8330) 
multiplier. 
This alarm occurs only for a slave axis only. 

SV0003 SYNCHRONOUS/COMPOSITE/SUPERI

MPOSED CONTROL MODE CAN'T BE 
CONTINUED 

Since as axis in synchronization, composition, or 
superposition mode caused a servo alarm, the mode could 
not be continued, If one of the axes in a mode causes a 
servo alarm, all axes relating to the axis enter the servo-off 
state. This alarm is generated to enable the cause of the 
servo-off state to be checked. 

SV0004 

EXCESS ERROR (G31) 

The amount of positional deviation during torque limit skip 
command operation exceeded the limit value of the 
parameter No.6287. 

SV0005 

SYNC EXCESS ERROR (MCN) 

In feed axis synchronization control, for synchronization, the 
difference value of the machine coordinate between a master 
and slave axes exceeded the parameter (No. 8314) setting 
value. 
This alarm occurs for a master or slave axis. 

SV0006 

ILLEGAL TANDEM AXIS 

For the slave axis under tandem control, absolute position 
detection is set (parameter bit 5 (APC) of parameter No. 
1815 = 1). 

SV0007 

SV ALM ANOTHER PATH(MULTI AMP.) 

When a multiaxis amplifier was used in a multipath system 
across paths, a servo alarm occurred on an axis belonging to 
another path. 
When a system with two or more paths and multiple servo 
axes between paths are controlled by a multiaxis amplifier, if 
a servo alarm occurs on an axis belonging to another path of 
the same amplifier, the MCC of the amplifier goes down and 
SV0401 V-READY OFF occurs on an axis belonging to the 
local path in the same amplifier.    Since SV0401 is caused 
by a servo alarm occurred on an axis in another path, 
SV0007 is caused together to clearly indicate the fact. 
The axis belonging to another path in the same amplifier 
resolves the cause of the servo alarm.
