*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 forces are the continuous allowable force values at a surrounding air temperature of 40°C with an aluminum
heat sink of the dimensions given in the following table.
