Commissioning
• Check that the drive elements (carriage, magnetic plate, coil unit) are tightly fastened and correctly
adjusted.
• Can the carriage move unhindered over the entire motor track without touching the magnet yoke?
• Are the mechanical end-stops, limit switches and buffers properly dimensioned, and are they
configured correctly?
• Is the thermal protection contact cable connected?
• Does the combination of the motor and the graduated rule have the correct polarity?
• Check the wiring and connections to the motor and the servo drive. Check that the earthing is correct.
• Test the function of the holding brake, if used.
• Check whether the carriage of the motor can be moved freely (vent the brake beforehand if there is
one). Listen out for grinding noises.
• Check that all the required measures against accidental contact with live and moving parts have been
carried out.
• Carry out any further tests which are specifically required for your system.
• Now commission the drive according to the commissioning instructions for the servo drive.
• In multi-axis systems, individually commission each drive unit (servo drive/motor(s)).
• Is the track free from foreign bodies?
• Are cables correctly guided?
9.2.3
Optimizing the control settings
Generally speaking, settings made to the current controller do not affect the motor performance. A wide
range is also available for adequate possible settings. The settings of the current control depend only on the
application parameters of the servo drive and of the motor.
Due to its sensitivity to oscillations, to noise and to delays, the speed control only has limited use as a factor
for servo drive power. Please take the time to adjust this controller correctly before the position controller is
optimized. In this respect, be sure to also read the instructions in the manuals for the servo drive employed.
Adjustment of the controller
The position controller can only be adjusted correctly if the speed controller has been adjusted cor-
rectly beforehand.
