- 1These values are for operation in combination with a SERVOPACK when the temperature of the armature winding is 100°C. The values for the other items are at 20°C. These are typical values.
- 2The rated forces are the continuous allowable force values at a surrounding air temperature of 40°C with an aluminum heat sink of the following dimensions:
- 150 mm x 100 mm x 10 mm: ST2F-A1A and ST2F-A1D
- 254 mm x 254 mm x 25 mm: ST2F-A2A, ST2F-A2D, ST2F-A3A, and ST2F-A3D
- 400 mm x 500 mm x 25 mm: ST2F-C1A and ST2F-C1D
- 609 mm x 762 mm x 40 mm: ST2F-C2A and ST2F-C2D
- 900 mm x 762 mm x 40 mm: ST2F-C3A and ST2F-C3D
- 3Units are assembled and tested fully restrained on a granite surface with a maximum surface accuracy of 15μm at 70°F. Performance of the installed unit may vary with mounting surface quality and temperature.
