Reduction Gears for SMARTSTEP A-series Servomotors (R7G-
@
)
There are two kinds of reduction gears for SMARTSTEP A-series Servomotors:
• Reduction gears for 3,000-r/min Cylinder-style Servomotors
(Backlash 3
′
max. and backlash 45
′
max.)
• Reduction gears for 3,000-r/min Flat-style Servomotors
(Backlash 3
′
max. and backlash 45
′
max.)
There are four reduction ratios: 1/5, 1/9, 1/15, and 1/25. Select a reduction ratio to match the ca-
pacity of the Servomotor.
Note There are no 30-W reduction gears for Cylinder-style Servomotors.

Max.
Note 1. The reduction gear inertia indicates the Servomotor shaft conversion value.
Note 2. The enclosure rating for Servomotors with reduction gears is IP44.
Note 3. The allowable radial torque is the value for the center of the shaft.
