Ratings of Servo Motors (200 V Models)
Note: The values in parentheses are for Servo Motors with Holding Brakes.
*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature winding is
100°C. The values for other items are at 20°C. These are typical values.
*2. The rated torques are the continuous allowable torque values at a surrounding air temperature of 40°C with an alumi-
num heat sink of the dimensions given in the table.
*3. This does not apply to the shaft opening. Protective structure specifications apply only when the special cable is used.
*4. Observe the following precautions if you use a Servo Motor with a Holding Brake.
• The holding brake cannot be used to stop the Servo Motor.
• The time required to release the brake and the time required to brake depend on which discharge circuit is used.
Confirm that the operation delay time is appropriate for the actual equipment.
• The 24-VDC power supply is not provided by Yaskawa.
*5. The allowable shaft loads are illustrated in the following figure. Design the mechanical system so that the thrust and
radial loads applied to the Servo Motor shaft end during operation do not exceed the values given in the table.
