Operation Considerations The motor must always be operated within the specified operating parameter limits.
Exceeding those limits will permanently damage the motor Refer to the motor
specifications for operating parameter limits.
The motor must never touch the magnets during operation. The air gap must be
maintained over full length of travel.
Remove the shim that sets the air gap between the motor and the magnets prior to
operation.
Note: Be aware that the total bearing load includes the magnetic attractive force.
The following steps must be completed to ensure safe and proper operation.
1. Verify that all electrical wiring and cables are properly connected. Refer to the
manual provided with the control for this information.
2. Adjust the servo drive current to match the motor’s current specification.
3. Refer to the motor specifications for operating parameters. Adjust the control
parameters as necessary to the motor data specifications.
4. Adjust the control for the proper P.I.D. loop tuning. Begin at a low gain setting
and increase the gain as necessary.
5. Strain relieve the wires prior to operating.
