· Please consult with NSK in case of a simultaneous application of axial load, radial load and moment load to a Motor.
· ＊1 Under no radial load ＊2 Under no axial load
· ＊3 Positioning accuracy with brake released
· For an oscillating operation less than 45 [°], turn the Motor 90 [°] or more at least once a day.
· Conditions outside the allowable range of inertia (about 400 times the rotor inertia) may be applicable, depending on operating conditions. Contact NSK for details.
· User’s manual and technical data are available for brake holding accuracy, operating time, and frequency of use. Contact NSK as necessary.

Note on compliance with UL Standards and CE Mark
· PN Series with Brake

PN Series with brake does not comply with UL Standards or CE Mark.
· EDC Driver Unit

E DC Driver Units comply with UL Standards and CE Mark when used with a Standard PN Series Megatorque Motor (without brake). However, they do not comply with UL
Standards or CE Mark when used with a PN Series Megatorque Motor with a brake.
