MDS-D/DH Series Specifications Manual
2-1 Servomotor
2 - 7
(2) 400V series
< HF-H Series >
(Note 1) The above characteristics values are representative values. The maximum current and maximum
torque are the values when combined with the drive unit.
(Note 2) Use the HF-H motor in combination with the MDS-DH Series drive unit compatible with the 400VAC
input. This motor is not compatible with the conventional MDS-B/C1/CH Series.
(Note 3) The total length will be 3.5mm longer when using an A51 or A74N detector.
