The motor requires a 3 phase brushless amplifier with power supply, which is rated with sufficient current and voltage to meet the motion requirements. The inductance of the linear motor coil should be greater than the minimum load inductance of the servo amplifier. A programmable motion controller is required to close the position loop on the system.
The stage is a precision device with sensitive components, it should not be mounted in an environment that is wet or excessively dirty. The optical encoder scale is open and it should be kept free of debris in order to operate properly. The stationary magnetic assembly is highly magnetic, it should not be placed in an area where loose steel particles can be drawn into the magnetic gap. The stage must not be mounted in an environment with high ambient temperatures (>50ºC).
The stage should be mounted to a flat and stiff surface. Counter bored thru holes are present in the stage to allow for the mounting of the stage to the customer’s system. The moving table assembly has threaded holes on the top surface for attaching the payload. The stage may be mounted in any orientation. When mounting the stage with the table moving vertically, it should be noted that the stage will be required to generate additional force due to gravity. If a vertical brake is not installed, the stage will slide down (drop) to the bottom hard stop when power fails.
The air bearing shafts should also always be free of any contaminants that may prevent proper airflow. If the air bearing or riding surface ever needs to be cleaned, it may be wiped down using lint free Kim wipes and isopropyl alcohol (do not use acetone). The air bearing shafts may also be cleaned the same way. Be sure that the parts are dry before applying any power to the stage and attempting to move it.
