8.4 Maintenance checks
During each service interval, the following measurement/
check needs to be done:
• LS: the axial play must be less than the following values:
CASM–32 CASM–40 CASM–63
0,35 mm
0,6 mm
1,0 mm
If the play is above the specified values, the drive needs to
be replaced. If not replaced, it could lead to catastrophic
failure of the system (uncontrolled movement of the mov-
ing mass).
• BS: excessive wear of the ball screw could lead to a noise
increase and a potential blockage of the drive
• In the case of the U-shape (belt drive), check:
-
the tooth belt for sign of early fatigue (cracks and/or
heavy wear)
-
replace after 2 million cycles without regard for wear
• Setting data (⮑ 7.6.5 Timing belt installation, page 20)
WARNING

• Do not operate the system when the gearbox cover is removed.
