◊ The load moment of inertia to a Motor must be 70 times or less than the Motor inertia
(100 times for the PS1, PS3 and PN2 type Motors). In case of an indexing operation, a
position command shall be 360 degrees or less, while the maximum speed for
continual rotation must be 0.5 [s
-1
] or less.
(However, there may be a possibility to exceed the above limits in some cases. Please
consult NSK when you require a close investigation on the limits.)
◊ For the PN4180 Motor, be sure to stop the Motor for 20 minutes or longer when you
stop it by the dynamic brake.
！
Caution: When the Motor is continually accelerating a high inertial load with high
acceleration, the system constantly outputs a high torque exceeding
the rated torque, and thus likely to activate the warning “A3” (Software
thermal). In such a case take a remedy to decrease the load moment
of inertia or to lower the speed.
