Notes
1. An optional cover provides an 8.9mm (0.35 inch) diameter hole through the housing for longer motor shaft.
2. Encoder must be aligned as shown in the “Encoder Mounting and Assembly” instructions.
3. The recommended mounting screw torque for 2 screw mounting is 1.0 kg-cm (0.88 in-lbs). The recommended mounting screw torque for 3 screw
mounting is 0.50 kg-cm (0.43 in-lbs).
