Multiple Coil Assembly Operation
In addition to maintaining an air gap, multiple coil assemblies must also maintain a spacing factor of 1.8″ . In other words, the space between coil assemblies may vary, however, the distance from the front end of the first coil assembly to the front end of the next must be a multiple of 1.8″ . See Figure
Ensure that this spacing is established at the time of installation.

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. Refer to “Adjust Air Gap”.
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 control continuous current limit to match the motor’s continuous current specifications.
3.Adjust the servo drive current to match the motor’s current specification.
4.Refer to the motor specifications for operating parameters. Adjust the control parameters as necessary to the motor data specifications.
5.Adjust the control for the proper P.I.D. loop tuning. Begin at a low gain setting and increase the gain as necessary.
6.Strain relieve the wires prior to operating.
