Box or put the Teaching
Box into T. BOX LIMITED
Mode.

Another axis control bit is ON
at the same time.
Check whether another axis con-
trol bit is ON at the same time.
Try executing servo-lock using
the Teaching Box.
Turn OFF the other axis
control bit and turn ON
the servo-lock bit.
(Change the ladder
program.)
11
The MC Unit is defective.
Replace the MC Unit.
12
The motor is not

The servo is not locked.
Check whether the Servo Driver
is operating.
Check the MC Unit axis status to
see whether servo is locked.
Execute servo-lock and
then turn the motor.
(Change the ladder
program.)
13
The wiring is incorrect
between the MC Unit and the
Servo Driver.
Check the wiring with a tester.
Change the connecting cables.
Correct the wiring.
14
A run prohibit input, such as
POT or NOT, is ON for a
U-series Servo Driver (when
Cn-01 bits 2 and 3 are 0).
Check the run prohibit inputs.
Turn OFF the Servo
Driver run prohibit input.
Make the setting so that
the Servo Driver run
prohibit inputs will not be
used.
15
The Servo Driver is in the
internally set speed control
mode (and is not receiving
MC Unit speed referenced).
Check the Servo Driver setting.
Correct the Servo Driver
setting.
16
A Servo Driver alarm has
been generated.
Check the contents of the Servo
Driver alarm.
If there is an alarm, then
follow the instructions.
