1. The rated torque is the permissable continuous torque at the operation temperature of 0~40˚C when the following heat sink is applied: ECM-A3: 04/06/ 08 : 250 mm x 250mm x 6mm __ Material type: Aluminum- F40, F60, F80 2. The built-in brake of the servo motor is for calmping the shaft. Never use it for decelerating or stopping the motor
