Function and application
Main opti
on
Ferrite ring reactors for
reducing radio frequency
noise
(ACL)
An ACL is used to reduce radio noise emitted by the inverter.
An ACL suppresses the outflow of high frequency harmonics caused by
switching operation for the power supply (primary) lines inside the
inverter. Pass the power supply lines together through the ACL for 4
turns (coiled 3 times).
If wiring length between the inverter and motor is less than 20 m, insert
an ACL to the power supply (primary) lines; if it is more than 20 m, insert
it to the power output (secondary) lines of the inverter.
External potentiometer
for frequency commands
An external potentiometer may be used to set the drive frequency.
Connect the potentiometer to control signal terminals [11] to [13] of the
inverter.
Remote keypad
This allows you to perform remote operation of the inverter.
With the remote keypad, you can copy function code data configured in
the inverter to any other inverter.
Keypad models: TP-E1U and TP-E1
Extension cable for
remote operation
The extension cable connects the remote keypad with the inverter for
remote operation. It is also used for connection of a USB–RS-485
converter.
Three lengths are available: 5 m, 3 m and 1 m
USB–RS-485 converter
A converter is used to easily connect the RS-485 communications port
to a USB port on a PC.
(Products supplied by System Sacom Sales Corporation are

Inverter loader software
Windows-based inverter loader software that makes it easy to configure
function code data via the GUI (graphical user interface).
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 killers
A surge killer eliminates surge currents induced by lightening and noise
from the power supply lines. Use of a surge killer is effective in
preventing the electronic equipment, including inverters, from damage
or malfunctioning caused by such surges and/or noise.
Arresters
An arrester suppresses surge currents and noise invaded from the
power supply lines. Use of an arrester is effective in preventing
electronic equipment, including inverters, from damage or
malfunctioning caused by such surges and/or noise.
