MDS-D/DH Series Specifications Manual
2-1 Servomotor
2 - 3
< HF 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 motor in combination with the MDS-D Series drive unit compatible with the 200VAC 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.
