6-1-2 Precautions When Troubleshooting
When checking and verifying I/O after a problem has occurred, the Servo Driver may
suddenly start to operate or suddenly stop, so always take the following precautions.
In addition, never attempt operations that are not specified in this manual.
Precautions
•
Disconnect any cables before checking whether they are broken or damaged. Even
if you have checked the conduction of the wiring, there is a risk of conduction due to
the return circuit.
•
If the encoder signal is lost, the Servomotor may overrun, or an error may be
generated. Be sure that the Servomotor is disconnected from the mechanical
system before checking the encoder signal.
•
When performing tests, first check that there are no personnel in the vicinity of the
mechanical equipment, and that the equipment will not be damaged even if the
Servomotor overruns. Before performing the tests, verify that you can immediately
stop the machine using an emergency stop even if the Servomotor overruns.
6-1-3 Replacing the Servomotor and Servo Driver
Use the following procedure to replace the Servomotor or Servo Driver.
Replacing the Servomotor
(1) Replace the Servomotor.
(2) Perform origin teaching.
•
When the Servomotor is replaced, the Servomotor’s specific origin position
(Z-phase) may slip, so origin teaching must be performed.
•
Refer to the Position Controller’s manual for details on performing origin
teaching.
Replacing the Servo Driver
(1) Replace the Servo Driver.
(2) Match the previous switch settings.
•
Set the new Servo Driver’s switches (command pulse setting rotary switch and
command filter setting rotary switch) to match the old Servo Driver’s switch
settings.
