2-axis AC Servo Amplifier MR-J3W-0303BN6
AC Servo Motor HG-AK Series
Notes: 1. The power supply capacity varies depending on the impedance of DC power
supply and wiring.
2. When unbalanced torque is generated, such as in a vertical lift machine, it is
recommended that the unbalanced torque of the machine be kept under 70%
of the servo motor rated torque.
3. The regenerative braking frequency shows the permissible
frequency when the servo motor, without a load and a
regenerative option, decelerates from the rated speed to a stop.
When a load is connected; however, the value will be the table value/(m+1),
where m = Moment of inertia of load/Moment of inertia of servo motor.
When the operating speed exceeds the rated speed, the regenerative
braking frequency is inversely proportional to the square of (operating speed/
rated speed). Take measures to keep the regenerative power [W] during
operation below the tolerable regenerative power of built-in regenerative
resistor [W]. Use caution, especially when the operating speed changes
frequently or when the regeneration is constant (as with vertical feeds).
4. Contact your local sales office if the load to motor inertia ratio exceeds the
value in the table.
5. In the environment where the servo motor is exposed to oil mist, oil and/or
water, a standard specification servo motor may not be usable. Contact your
local sales office for more details.
6. The vibration direction is shown in the diagram
to the right. The numerical value indicates the
maximum value of the component (commonly the
bracket in the opposite direction of the servo motor
shaft). Fretting more likely occurs on the bearing
when the servo motor stops. Thus, maintain
vibration level at approximately one-half of the
allowable value.
7. Refer to the diagram to the
right for the permissible load
for the shaft. Do not apply
a load exceeding the value
specified in the table on the shaft. The values in the table are applicable
when each load is applied singly.
8. The shaft-through portion, the connector, and
the power cable leading part are excluded.
Refer to the diagram to the right for shaft-
through portion.
9. V10 indicates that the amplitude of the servo
motor itself is 10 µm or less. The diagram
to the right shows mounting posture and
measuring position of the servo motor during the
measurement.
