MDS-D/DH Series Specifications Manual
2-3 Tool spindle motor
2 - 47
< 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) A 2-axis spindle drive unit (MDS-D-SP2) drives two tool spindle motors only. A spindle motor other than
tool spindle motor is not usable.
