

The above characteristics apply when the rated AC voltage is input from the drive unit. Output and rated motor speed are not guaranteed when the power

supply voltage drops.



The power supply capacity varies with the value of the power supply side drive unit impedance (including those of the input reactor and cables).



When the motor is used with a machine that produces unbalanced torque such as an elevating axis, the unbalanced torque should be 70% of the rated

torque or lower.



This is the ratio of the moment of load inertia to the moment of motor inertia under position control. If the load inertia moment ratio exceeds the described

value, please contact your sales representative.



This excludes the part where the shaft passes through. For the motor with a reduction gear, the protective structure of the reduction gear part is equivalent to IP44.



X indicates the direction of the motor's output shaft, and Y indicates the direction vertical to the motor's output shaft. Usually, the indicated value is of the

non-load side bracket where the vibration is the greatest.

Bearing is subject to fretting while the motor is stopped. Suppress the vibration to about the half of the permissible value.



The standard motor may not be used under the condition where it is constantly exposed to oil mist, oil, or water. For the details, please contact your sales

representative.



V10 indicates that the vibration amplitude by only a motor is 10m or lower. The following figure shows the installation orientation of the motor and

measurement position when the degree of vibration is measured.



For the permissible load on the shaft, refer to the following figure. Do not apply a load exceeding the value in the table to the shaft.

Each value in the table is for when only one load is applied.
