11.7.4 Driving Belt Replacement
Items required for the Replacement
• Replacement Driving Belt • Packing Tape • 8 mm Spanner Wrench • Hexagon Wrench Set
• Push-Pull Gauge and Square • Personal Computer or Teaching Pendant
• Tension Gauge (Tension of 10 kgf or more available) • Strong Thread (or Long Harness Belt)
Replacement Operation Outline
1) Loosen the tension adjusting bolt and replace the belt. Then, fasten the adjusting bolt until the specified tension value is
reached.
2) Perform the homing operation.
Loosen the deceleration belt and then, move the slider to the mechanism end and fix it. Then, fix the motor shaft at the
position about 90 degrees deviated from the counter mark and adjust the deceleration belt to reach the specified tension
value.
3) Perform the homing operation using the personal computer or teaching pendant and confirm the deviation from the
original home position. If there is any deviation, adjust it using the home offset value in the parameters.
Note: For the home offset for E/G controller, any negative value can not be entered. Therefore, deviate the position
slightly less than 90 degrees.
Procedure
1) Confirm the motor shaft rotating direction when the slider is moved from the home position to the mechanism end.
(The rotating direction varies depending on the motor installation position. Therefore, the confirmation is always required).
• Motor Side • Opposite Side
2) Remove the belt cover.
Remove the set machine screw (4 locations) on the motor side and also the opposite side. (Use the hexagon wrench with
the distance to the opposite side of 2 mm).
• Remove the pulley cover.
(Use the hexagon wrench with the distance to the
opposite side of 1.5 mm for IF-S or 2 mm for IF-M).
• Confirm the motor shaft rotating direction.
