The motor rotated in the
direction opposite to the
command. There is incorrect wir-
ing of the motor cable or
a broken cable. Connect the motor cable as shown
in the wiring diagram. If the cable is
broken, replace it.
Or, connect the motor cable and
encoder cable that are used
together to the same motor.
The motor rotated in the
direction opposite to the
command by external
forces. Take countermeasures so that the
motor is not subjected to external
forces.
Set
Runaway Detection - Enable
(3B71-01 hex) to 0 (disabled) when
the motor runs as intended.
21 00 Encoder
Communica-
tions Discon-
nection Error The communications
disconnection was
detected between the
encoder and the Servo
Drive.
This error is detected if
the encoder communi-
cations timeout occurs
four times in a row. Noise into the encoder
cable • Separate the motor cable and the
encoder cable if they are bundled
together.
• Connect the shield to FG.
• Confirm that the motor ground
wire is connected to FG.
Contact failure of the
signal line, and discon-
nection of the encoder Replace the encoder cable if it is
broken. Firmly connect the encoder
connector to the Servo Drive.
Power supply undervolt-
age to the encoder Use the recommended encoder
cable.
Encoder failure If this event occurs after you per-
formed all corrections shown
above, replace the motor.
01 Encoder
Communica-
tions Error Illegal data was
received from the
encoder the specified
number of times.
This error is detected if
the data error occurs
four times in a row
during communications
with the encoder. Noise into the encoder
cable • Separate the motor cable and the
encoder cable if they are bundled
together.
• Connect the shield to FG.
• Check that the motor ground wire
is connected to FG.
Contact failure of the
signal line, and discon-
nection of the encoder Replace the encoder cable if it is
broken. Firmly connect the encoder
connector to the Servo Drive.
Power supply undervolt-
age to the encoder Use the recommended encoder
cable.
