Name of option Function and application
Main option
Ferrite ring reactors for
reducing radio frequency noise
(ACL)
An ACL is used to reduce radio-frequency noise emitted by the drive.
An ACL suppresses the outflow of high frequency harmonics caused by the switching
operation in the drive’s internal power supply lines. Pass the power supply lines together
through the ACL.
If wiring length between the drive and motor is less than 66 ft (20 m), place an ACL around the
power supply lines; if it is more than 66 ft (20 m), put it in the power output lines of the drive.
Options for 100 V single-phase
power supply
An optional 100 V single-phase power supply may be used to operate a drive designed for a
230 V 3-phase power supply.
Options for Operation and
Communications
External potentiometer for
frequency command
An external potentiometer may be used to set the drive frequency. Connect the potentiometer
to control signal terminals 11 to 13 of the drive.
Remote keypad Used when performing drive remote operations with the remote keypad.
Extension cable for remote
operation
The extension cable connects the drive with the remote keypad to enable remote operation of
the drive.
RS485 communications card For communicating with a PLC or personal computer system.
Drive support loader software The Windows-based drive support loader software makes setting function codes easy.
Requires use of the RS485 communications card.
Other peripheral equipment
Surge absorbers A surge absorber suppresses surge currents and noise from the power lines to ensure
effective protection of your power system from the malfunctioning of the magnetic contactors,
mini-relays and timers.
Surge suppressor A surge suppressor absorbs high surge currents induced by lightning, and noise from the
power supply lines. Use of a surge suppressor is effective in preventing electronic equipment,
including drives, from damage or malfunction from these causes.
Arresters An arrester suppresses surge currents and noise from the power supply lines. Use of an
arrester is effective in preventing electronic equipment, including drives, from damage or
malfunctioning caused by such surges and/or noise.
Frequency meter Displays the frequency in accordance with signal output from the drive.
Other options
Mounting adapters The AF-300 Mini series of drives can be installed in the control board of your system using
mounting adapters which use the mounting holes intended for conventional drives (E11 series
of 1 hp or below, or 5 hp). The E11S (2 hp/3 hp) and E11 (1 hp/2 hp) series may be replaced
with any of the AF-300 Mini series drives without the use of adapters.
Rail mounting bases A rail mounting base allows any of the AF-300 Mini series of drive to be mounted on a 35 mm
standard DIN rail.
