Combine multiple weights on a rotor

Overview

The Sum Weights option lets you enter up to three known or desired weights and angular locations to calculate the weight sum. Use Sum Weights to combine some weights on the rotor.

If you open this option from a trim run, you can send the calculated solution to the trim run screen.

Procedure

  1. From the Balance main menu, press ALT > F6 Calculator Mode > F3 Sum Weights.
  2. Set the following options as necessary.
    Option Description
    F2 View Balance Corr. View the last balance correction. This option displays only if the analyzer calculated a balance correction and you accessed Sum Weights from the Trim Run Applied Weight menu.
    F3 - F5 Enter a number up to 10,000 for a weight value. You can also import the value from the Balance Correction menu. This field is unitless. If you opened Sum Weights from the Trim Run Applied Weight screen, the units are as defined for the job.
    F9 - F11 Enter a number for the desired weight angle or position. The default is 0 or 1, depending on if you use continuous or discrete weight planes. You can also import the value from the Balance Correction menu. If you defined discrete weight positions and you import the value, the keys display Enter Position rather than Enter Angle.
  3. Press F1 Calculate Solution or Enter.
    The Sum Weights Solution screen lists the location and amount of weight to place on the rotor. To change the rotation direction, press F6 Toggle Direction Rotation.
  4. If you opened Sum Weights from a trim run, press F12 Insert to Trim Weight to send the calculated solution to the Trim Run Applied Weight entry.
  5. Press F7 Sum Weights Calc to exit and return to the calculation screen.
