1 The current input (Pr. 904, Pr. 905 ) can also be
adjusted using a similar procedure.
2The Pr. 903 Terminal 2 frequency setting gain remains
unchanged even if the Pr. 20 Acceleration/
deceleration reference frequency setting is changed.
3 A narrow calibration (command) value set using Pr.
902 and Pr. 903 (Pr. 904 and Pr. 905) will result in "Incr
