Countermeasure
d03
Faulty encoder or attachment of
dust
The encoder is faulty or dust is attached.
Remove the motor cover and apply cleaning air spray for OA
equipment, etc., over the cord wheel.
If the problem persists, replace/readjust the encoder.
d06
Encoder received-data error
The encoder cable is disconnected.
Replace the encoder cable.
The motor coil is damaged.
Measure the inter-phase resistances among U, V and
W. If the measured resistances are not the same, burn
damage is suspected. Replace the motor.
If the measured resistances are roughly the same,
there is no burn damage.
690
Motor overcurrent error
If the motor coil is not damaged, the driver’s
CPU board (the board to which the motor
drive cable is connected) is faulty.
Replace the board.
d19
Encoder receive timeout error
The encoder cable is disconnected.
Replace the encoder cable.
d18
Speed loop underrun error
The driver CPU board was damaged due to
noise in the encoder cable.
Replace the board and implement noise control measures.
807
Shutdown relay ER status
The transistor on the power-supply board (to
which the power cable is connected) is
damaged.
Replace the board.
