3006h • The axis entered the software limit area in
negative direction during axis movement
with the origin defined. Check if the set-
ting value of the axis parameter [P3AA02:
Negative direction software limit] is cor-
rect. (The error may occur when execut-
ing circular interpolation right on the
software limit values.) If the setting value
is incorrect, set a larger limit value. When
the value is correct, correct the program
or travel distance of the axis.
3007h • The axis that received a movement com-
mand is in Servo OFF state. (In opera-
tions with programs, this alarm will occur
when the applicable axis is specified at
the beginning of the block and a move-
ment command is executed for the axis
that is in Servo OFF state.) Switch the
axis to Servo lock state.
• Servo OFF was executed for the axis
receiving a movement command.
Do not execute Servo Unlock during axis
movement.
An error was occurred in the MECHA-
TROLINK synchronous communications.
The followings are the possible causes:
• Disconnection, breakage of MECHA-
TROLINK cable
Check the MECHATROLINK cable.
• Communications error caused by noise
Remove the cause of the noise.
When this error persists even after provid-
ing these remedies, the Driver (NS115) or
MC Unit may be broken. Replace the bro-
ken one with a new unit.
Detected MECHATROLINK communica-
tions errors twice in a row. Or the No. of
error detections specified in [P1AA06:
MECHATROLINK-II communications error
detection setting] has been exceeded. The
followings are the possible causes:
• Disconnection, breakage of MECHA-
TROLINK cable
Check the MECHATROLINK cable.
• Communications error caused by noise
Remove the cause of the noise.
When this error persists even after provid-
ing these remedies, the Driver (NS115) or
MC Unit may be broken. Replace the bro-
ken one with a new unit.
