200 mA.
Analog inputs AI 1 analog voltage input AI1: range 0-10 V, impedance 30 k Ω .

[1] The maximum allowable input line unbalance is
5% for 460 V input line short circuit capacity of
15,000 A, 2.5% for 460 V input line short circuit
capacity of 30,000 A, 0.5% for 460 V input line short
circuit capacity of 65,000 A. If the resulting voltage
harmonic distortion exceeds 5%, three phase line
reactors are recommended.
[2] Input voltage is 460 V, -10%, +15% on
ATV58HU54N4X–D23N4X controllers as rated in the
table on page 9. Input voltage is 400 V -15% to 460 V
+10% on ATV58C10N4X–C33N4X.
[3] See page 26 and following for available accessories
and options.
[4] The drive controller can be configured to reduce
switching frequency if the drive thermal state reaches
95%. When the drive thermal state returns to 70%, the
switching frequency returns to the set value. If the duty
cycle (drive controller run time) does not exceed 60%
(36 second maximum for a 60 second cycle) derating is
not required.
[5] Motor thermal protection can be set between 25
and 136% of the drive controller rating.
