In operation
CAUTION!
Risk of injury from touching hot surfaces.
The motor connecting kit becomes hot due to the heat dissipation of the motor.
•
Do not touch the motor connecting kit during operation or immediately after-
ward.
WARNING!
Risk of injury due to unexpected movement of components if toothed belt fails.
•
Take supplemental safeguarding measures.

Maintenance
7.1
Check the toothed belt
The toothed belt [5] is a wearing part
è
www.festo.com/spareparts.
1. Check toothed belt [5] regularly:
–
during maintenance of the machine
–
when replacing an axis
2. Replace the toothed belt [5] at the following indicators of wear:
–
excessive accumulation of wear particles in the housing
–
cracks on the back of the toothed belt
–
visible glass fibre cords in the tooth base
Fig. 20 Loosen toothed disc
1. Unscrew the screws [2] slightly.
Ä
The motor is movable and can be easily tilted.
2. Move the motor in the direction of the axis up to the stop and tilt it slightly.
3. Dismount the counter bearing.
4. Unscrew the toothed belt pulleys [6]. Apply counter pressure to the clamping
sleeves [3]/[4].
5. Rotate toothed belt pulleys [6] anti-clockwise.
Ä
The toothed belt pulleys [6] can be pulled from the cone of the clamping
sleeves [3]/[4].
7.2
Dismounting the toothed belt

Tightening torques for the toothed belt pulleys
The transmittable torque depends on the tightening torque of the toothed belt
pulleys [6].
•
Select the tightening torque of the toothed belt pulley [6] from the permiss-
ible range.
Ä
Check: The transferable torque is greater than the driving torque of the
motor
