NOTE: If the carrier frequency is set higher

than 10 KHz and an internal overheating
condition occurs, the drive will auto-
matically reduce the carrier frequency to
10 KHz in order to avoid an overheating
fault (available up to 30 Hp only).

OL LEVEL

OVERLOAD LEVEL

RATED

The overload level for the electronic

CURRENT

overload protection algorithm (see Function
Code 08) can be adjusted from the factory
default setting of rated drive nameplate amps.
For example, if a 20 Hp/30A motor were
applied to a 30 Hp/45A drive, you would
change Function Code 09 from 45 to 30 amps to
protect the motor. The setting range is
approximately 20 to 135% of rated drive current.

The AF-300E$ family of Drives are
designed to tolerate an AC line voltage dip
to 165V (230 VAC), 310V (230 VAC),
400V (575 VAC) 70% for 15 msec at 85% of full load
without any disturbance in output power delivered
to the load. However, in the event of a more
serious power dip or outage, the drive may
act in one of five ways depending on the
setting of this Function Code.
