(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-R Series drive unit compatible with the 200VAC input.
This motor is not compatible with the conventional MDS-B/C1/CH Series.
(Note 3) The shaft-through portion is excluded.
(Note 4) "( )" indicates the combination with the drive unit capacity of one rank up. The motor characteristics are same as the
characteristics applied when the drive unit capacity is standard.
