12 Troubleshooting and Maintenance
*3 When Motor Velocity Demand Value After Filtering is forced to 0 during an immediate stop due to a halt or Positive/
Negative Drive Prohibition Input, the speed deviation immediately increases. The speed deviation also increases when
the Motor Velocity Demand Value After Filtering starts. Therefore, provide enough margin when making the settings.
*4 This operation is performed for safety and is not an error.
*5 The initialization of position data occurs at any of the following four timings.
After the control power was turned ON, after a Config operation, after FFT was executed, and after a trial run was
executed

Check the specifications of the
communications state change
command for the host controller.
Check the specifications of the
communications state change
command for the host controller.
• Connect the EtherCAT
communications cable correctly.
• Check to see if the EtherCAT
communications cable is exposed
to excessive noise.
• Check that the host controller
completed communications before
a interruption is generated in the
synchronous cycle (SYNC0 cycle).
Replace the Servo Drive.
• Check the operation of the host
controller.
• Connect the EtherCAT
communications cable correctly.
