7.1.1 Practical Example
Automatic width control failure (The case of SPPG1)
Problems Rail width does not become the setting width.
Causes Origin malposition of pulse motor. Looseness of the motor pulley of the pulse motor.
Remedies Adjust the origin position and return the origin.
ST axis origin detection error (The case of SPPG1)
Problems ST axis origin detection error occurs during the machine operation.
Causes
Since the looseness of the bearing fixed nut (with set screw) of the ST axis ball screw on
the servo unit section occurred, the inner bearing holder collar loosened and the
clearance was made between the bearing holder and the bearing.
The cause of looseness of the fixed nut is because the directions of set screw related for
tightening were not correctly on the design drawing. Therefore, since the set screw was
tightened without anaerobic adhesive (Loctite), the looseness of the set screw happened
by the progress of time.
Remedies
Tighten the bearing fixed nut and set screw of the ST axis ball screw and adjust the origin
position. Then return to origin.
To prevent the recurrence, insert the set screw which applied loctite to the nut and tighten
it to fix.
Calibration error (The case of SPPG1)
Problems The calibration error was not detected.
Causes Memory switch setting failure
Remedies
Screen clamp check marks ’NO’. (8000)
