9.1 Relevant parameters for remote Potentiometer speed control
If the integrated dial on the keypad 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 EFC
5610 is cabinet-mounted) or on the machine
itself.
A Potentiometer of
rating should be
used.
10kOhm
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.
If the rotation of the Potentiometer is the
opposite to that required (ie. turn anti-
clockwise to increase speed instead of
clockwise) reverse conne10V and
GND.
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 AI1 terminal at the Inverter
end. It is this voltage which provides the speed
signal with 0V being slowest and 10V fastest.
Use shielded cable between Potentiometer
and Inverter and ensure that the cable screen
is connected to the Inverter earth terminal only.
9.2 Connecting the Potentiometer
The default output frequency at 0V is 0Hz and
at 10V is 50Hz.
