0
Drive prohibition input
error 1
When the Drive Prohibition Input
Selection (Pn504) was set to 0, both
the Forward Drive Prohibition Input
(POT) and the Reverse Drive
Prohibition Input (NOT) turned ON.
When object Pn504 was set to 2,
either the Forward Drive Prohibition
input or the Reverse Drive Prohibition
input turned ON.
Check for any problems with the
switches, wires, and power supplies
that are connected to the Forward
Drive Prohibition input or the Reverse
Drive Prohibition input. In particular,
check to see if the control signal power
supply (12 to 24 VDC) turned ON too
slowly.

Drive prohibition input
error 2
When object Pn504 was set to 0,
MECHATROLINK-II communications
were interrupted and either POT or
NOT was ON, an operation command
(such as a trial run or FFT) was
received from the CX-Drive.
Conversely, POT or NOT turned ON
while operation was being performed
for a CX-Drive operation command.
40 0
Absolute encoder
system down error
The voltage of the built-in capacitor
dropped below the specified value
because the power supply to the
encoder or the battery power supply
was down.
Connect the battery power supply,
and then set up the absolute encoder.
Unless the absolute encoder is set up,
the alarm cannot be cleared.
41 0
Absolute encoder
counter overflow error
The multi-rotation counter of the
encoder exceeded the specified
value.
• Set the Operation Switch when
Using Absolute Encoder (Pn015)
to an appropriate value.
• Make sure that the traveling
distance from the origin of the
machine is no more than 32,767
revolutions.
42 0
Absolute encoder
overspeed error
The Servomotor rotation speed
exceeded the specified value when
only the battery power supply was
used during a power interruption.
• Check the power supply voltage
(5 VDC ± 5%) at the encoder.
• Check the connections to
connector CN2. Unless the
absolute encoder is set up, the
alarm cannot be cleared.
43 0
Encoder initialization
error
An encoder initialization error was
detected.
Replace the Servomotor.
44 0
Absolute encoder 1-
rotation counter error
The encoder detected a 1-rotation
counter error.
Replace the Servomotor.
45 0
Absolute encoder multi-
rotation counter error
The encoder detected a multi-rotation
counter error.
Replace the Servomotor.
47 0
Absolute encoder
status error
The rotation of the encoder was higher
than the specified value when the
power supply was turned ON.
Do not let the Servomotor move when
the power supply is turned ON.
48 0 Encoder phase-Z error
A missing incremental encoder phase-
Z pulse was detected. The encoder is
faulty.
Replace the Servomotor.
49 0 Encoder CS signal error
A logic error was detected in the CS
signal for incremental encoder.
The encoder is faulty.
Replace the Servomotor.
