AUTO ROTATION CALIBRATION
NOTICE
For proper operation, weld head rotation speed must be calibrated for the power
supply it is connected to. If weld heads are switched they must be re-calibrated
on the system before welding commences.
Weld Head ROTATION speed can be calibrated AUTOMATICALLY by the M-
207A or MANUALLY by the user. See Section 5.9 for MANUAL calibration.
The following procedure applies to the AUTO CAL feature for M-9 and M-96
type welding heads only, any other weld head will probably require MANUAL
calibration:
1. Insure that the weld head is connected per section III and the M-9 manual.
Rotation speed calibration is done automatically by the M-207A by moving
the rotor and measuring actual speed. Before proceeding CHECK THAT
THE ROTOR IS FREE TO ROTATE SAFELY and check that the M-207A
operate mode switch is set to OPERATE or PROGRAM.
2. To use the automatic calibration function press the SET UP key. This can be
done from the STATUS screen or a WELD SCHEDULE screen. Then press
the F key under HEAD CAL and the following screen will appear:
