10.1 Connecting the Potentiometer
If the up and down speed control buttons on
the keypad are 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 650 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.
10kOhm
To use a external potentiometer, the Inverter
must be set to operate in “Remote” mode - see
section 9 for details.
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 terminal 2 (AIN1) at the Inverter
end. It is this voltage which provides the speed
signal with 0V being slowest and 10V fastest.
The default speed at 0V is 0%. To change this,
edit parameter P3.
The default speed at 10V is 50Hz or 60Hz
depending on region. To change this, edit
parameter P2.
If the rotation of the Potentiometer is the
opposite to that required (ie. turn anti-
clockwise to increase speed instead of
clockwise) reverse connections +10V and 0V.
Use shielded SY cable between Potentiometer
and Inverter and ensure that the cable screen
