[Replacement Operation Outline]
1) Loosen the bolt fixing the motor bracket and replace the belt.
2) Perform the homing operation.
Move the slider to the mechanism end and fix it. At the same time, 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 45 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).
• Remove the pulley cover. • Confirm the motor shaft rotating direction.
(Use a hexagon wrench with the
distance to the opposite side of 1.5 mm
for IF-S or 2 mm for IF-M).
