2. The above specifications show the values under the cooling condition when a heat sink (aluminium board)
listed in the following table is mounted on the coil assembly.
The values of peak speed in the table indicate the maximum speed that can be controlled from SERVOPACK. Refer to
Force and Speed Characteristics for the actual motor peak speed.
(b) With High-force Magnetic Ways
The following table shows the ratings and specifications when the high-force magnetic ways are used.
