Precautions When Troubleshooting
Replacing the Servomotor and Servo Drive
Precautions
Replacing the Servomotor
Replacing the Servo Drive
1. Replace the Servomotor.
2. Perform origin position alignment (for position control).
3. Set up the absolute encoder.
1. Copy the parameters.
2. Replace the Servo Drive.
3. Set the parameters.
4. Set up the absolute encoder.
When checking and verifying I/O after a problem has occurred, the Servo Drive may suddenly start
to operate or suddenly stop, so always take the following precautions.
You should assure that anything not described in this manual is not possible with this product.
• Disconnect the cable before checking for wire breakage. Even if you test conduction with the cable
• If the encoder signal is lost, the Servomotor may run away, or an error may occur. Be sure to
• When measuring the encoder output, perform the measurement based on the SENGND (CN1 pin
• When performing tests, first check that there are no persons in the vicinity of the equipment, and
Use the following procedure to replace the Servomotor or Servo Drive.
• When the Servomotor is replaced, the Servomotor’s origin position (phase Z) may deviate, so
• Refer to the Position Controller’s manual for details on performing origin alignment.
• If a Servomotor with an absolute encoder is used, the absolute value data in the absolute encoder
• For details, refer to Absolute Encoder Setup Procedure on page 6-5.
Use the Parameter Unit or the operation keys on the Servo Drive to write down all the parameter
settings.
Use the Parameter Unit or the operation keys on the Servo Drive to set all the parameters.

connected, test results may not be accurate due to conduction via bypassing circuit.
disconnect the Servomotor from the mechanical system before checking the encoder signal.
13). When an oscilloscope is used for measurement, it will not be affected by noise if
measurements are performed using the differential between CH1 and CH2.
that the equipment will not be damaged even if the Servomotor runs away. Before performing the
tests, verify that you can immediately stop the machine using an emergency stop even if the
Servomotor runs away.
origin alignment must be performed.
will be cleared when the Servomotor is replaced, so setup is again required. The rotation data will
be different from before the Servomotor was replaced, so reset the initial Motion Control Unit
parameters.
