* These specifications and torque-speed characteristics are quoted with the motor used in combination with an SGDH servo
amplifier at an armature winding temperature of 20°C.
Note: These characteristics can be obtained when the following heat sinks (steel plates) are used for cooling purposes:
Type 2BDA to 3ZDA: 25.59 × 25.59 × 1.38 (in) (650 × 650 × 35 (mm))
Type 3GDA to 5EDA: 29.53 × 29.53 × 1.38 (in) (750 × 750 × 45 (mm))
