Loosen the steel belt adjustment screws sufficiently (about 5 times). If not done properly, the steel belt may cause damage when retaining the steel belt to the carriage.

 

Step 3: In order to prevent the steel belt from falling, when moving the carriage to the left (opposite side of the origin), fix steel the belt with acetate tape.

 

Step 4: Remove the screw retaining the steel belt (origin side).
A: Belt fixing screw

 

Step 5: Remove the steel belt from the CR speed deceleration pulley.
A: CR speed deceleration pulley
B: Steel belt

 

Step 6: Remove the CR motor cable from the CR motor.
A: CR motor
B: CR motor cable

Step 4: Assemble the tension gauge and the steel belt tension attachment.

 

Step 5: Press the tension gauge against the centre of the steel belt.
A: Steel belt
B: Tension gauge
C: Steel belt tension attachment

 

Step 6: Press the jig until the steel belt touches the Y rail, then gradually lower the pressure.
Value must be within the defined value when the steel belt and the Y rail are apart.

 

Note The steel belt tension specification is 0.98N+0.09N (100gf +10gf). The range within which the steel belt may move up or down on the pulley must be1 mm or less.

 

Step 7: If the tension of the steel belt is not within specification, adjust the tension with the steel belt tension screw.
