1-12 Operable range
The graphs below indicate the operable ranges of MMA series motors when combined with a
MELSERVO-J4 servo amplifier. For details, refer to [2-1 MMA series selection].
1. Continuous motion range
This indicates a range in which the motor can be operated continuously as shown by the relationship
between the torque and rotational speed. Note that values are measured with the radiation plate listed
on the graphs installed.
2. Motion range during acceleration and deceleration
This indicates a range in which the motor can be operated instantaneously as shown by the
relationship between the torque and rotational speed. This range is normally used for acceleration or
deceleration.

The continuous motion range represents an allowable range where the motor installed
on a specified aluminum radiation plate is operated under natural air cooling. If the
radiation area of the mounting member is small or heat conduction of the material is
poor, adjust the operating conditions to keep the rise in the motor's ambient
temperature to 40 K or less as a guide.
