If the integrated speed control dial is
unsuitable for the application, a remote
Potentiometer can be used instead.
This provides the benefit of allowing motor
speed to be controlled from a more convenient
location such as a cabinet door (if the iC5 is
cabinet-mounted) or on the machine itself.
A Potentiometer of rating should be
used.
The number of turns depends on the
application but both single turn and ten turn
Potentiometers are available from The Inverter
Drive Supermarket at InverterDrive.com.

9.2 Connecting the Potentiometer
A wiring diagram is shown in the illustration
opposite. The most important connection at
the Potentiometer end is the centre terminal or
“wiper”.
The wiper will output a variable voltage
between 0 and 10 volts and should be
connected to the V1 terminal at the Inverter
end. It is this voltage which provides the speed
signal with 0V being slowest and 10V fastest.
The default output frequency at 0V is 0.5Hz. To
change this, edit Parameter F25.
The default output frequency at 10V is 50Hz.
To change this, edit Parameter F26.
If the rotation of the Potentiometer is the
opposite to that required (ie. turn anti-
clockwise to increase speed instead of
clockwise) reverse connections VR and CM.
Use shielded SY cable between Potentiometer
and Inverter and ensure that the cable screen
is earthed at the green earth terminal on the
Inverter.
