Press , then
The present Pr. 903 setting
value appears.
When the set voltage is
changed, the % value also
changes.
The value selected in Pr. 73
(5V in this example) is 100%.

Voltage need not be applied
across terminals 2-5.

REMARKS
1 The current input (Pr. 904, Pr. 905) can also be
adjusted using a similar procedure.
2 The 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
I/P" and disable write.
