*1 When the power supply voltage drops, the continuous running duty and the speed cannot be guaranteed.
*2 If the load to motor inertia ratio exceeds the indicated value, contact your local sales office.
*3 The shaft-through portion is excluded. IP classifies the degree of protection provided against the intrusion of solid objects and water in
electrical enclosures.
*4 The vibration directions are shown in the following figure. The value is the one at the part that indicates the maximum value (normally
the opposite to load-side bracket). When the rotary servo motor stops, fretting is likely to occur at the bearing. Therefore, suppress the
vibration to about half of the permissible value. However, the description above is not applied to a geared servo motor is used.

*5 V10 indicates that the amplitude of a rotary servo motor as a single unit is 10 μm or less. The following figure shows the rotary servo
motor mounting position for measurement and the measuring position.

*7 Rotary servo motors with an oil seal have J in their model names. The HK-KT053W with an oil seal can be used at a derating rate of 80
%.
*8 The values in ( ) are for when the torque is increased.
*9 When IP67 cables are needed, contact your local sales office.
*10 If at 6000 r/min or less, the ratio will be 28 times or less.
*11 This is a recommended load to motor inertia ratio that is applicable when the servo motor is operated at the rated speed in combination
with the servo amplifier with a capacity of 100 W. When the servo motor is to be operated at a speed exceeding the rated speed, check
whether a regenerative option is required by using Drive System Capacity Selection Software Motorizer. The servo motor can be
combined with servo amplifiers with larger capacity.
*12 Refer to the following for geared servo motors.

*14 When a geared servo motor is used, the IP rating for the gear reducer area is equivalent to IP44.
