Hg-kr053 product specification remarks:

1. Ratio of load inertia to motor inertia.

2. Remove the through part of the shaft. With reducer, the reducer part is
about IP44.

3. When the unbalanced torque is generated like a lifting shaft, it is
recommended to control the unbalanced torque within 70% of the rated torque.

4. When decelerating from the rated speed operation state to the stop state, if
the actual torque is within the range of rated torque, there is no limit in the
regeneration frequency.

When decelerating from the maximum speed operation state to the stop state,
there is no limit in the regeneration frequency if the following conditions are
met.

. hg-kr053: the load inertia ratio is less than 8 times, and the actual torque
is within the rated torque range
