Note 1: The table above shows the values for the output shaft.
Note 2: The values obtained when combined with an MR-J4W2-0303B-MX940J servo amplifier (driven using an
ideal sine wave).
Note 3: All values shown are typical values.
Note 4: The values in brackets are resolution obtained when combined with an amplifier and multiplied by 4.
Note 5: Value with saturated temperature rise when installed on a 150 × 150 × 6 [mm] aluminum radiation plate.
Note 6: Value with 3× phase induced voltage.
