Error and Maintenance
44
Absolute encoder 1-turn
counter error
Occurs when the power
supply is turned ON.
• The encoder is faulty.
• Replace the
Servomotor.
45
Absolute encoder multi-
rotation counter error
Occurs when the power
supply is turned ON.
• The encoder is faulty.
• Replace the
Servomotor.
47
Absolute encoder
status error
Occurs when the power
supply is turned ON.
• The motor was moving
when the power supply
was turned ON.
• Do not let the motor
move when the power
supply is turned ON.
48
Encoder phase-Z error Occurs during operation.
• A phase Z pulse from
the encoder was not
detected regularly.
• Replace the
Servomotor.
49
Encoder PS signal error Occurs during operation.
• A logic error was
detected in the PS
signal from the encoder.
• Replace the
Servomotor.
50
External encoder
communications error
Occurs during operation.
• The disconnection
detection function was
activated because
communications
between the external
encoder and drive
were interrupted.
• Wire correctly.
• Fix the locations that
are disconnected.
• There was a
communications error
in data from external
encoder.
• Provide the required
external encoder
power supply voltage.
• Wire correctly.
• Connect the shield to
FG.
51
External encoder status
error
Occurs during operation.
• An external encoder
error code was
detected.
• Check the external
encoder specifications.
• From the front panel,
clear the external
encoder error, then
turn the power supply
OFF, then ON again.
55
Phases-A, B and Z
connection error
Occurs during operation.
• A disconnection or
other error was
detected in external
encoder phase A,
phase B, or phase Z
connection.
• Check the connection.
82
Node address setting
error
Occurs when the power is
turned on.
• The node address set
by the rotary switches
on the Drive exceeded
the setting range.
• Set the rotary switches
for node address
setting correctly. Turn
on the control power
again.
