Important: Control and signal functions affected by drive parameter
selection and programming are indicated on the following pages. Refer to
the Programming section in Chapter 5 for detailed parameter operating
descriptions.
Terminals 1, 2 and 3
These terminals are provided for connecting a remote 10k
Ω
, 2W
potentiometer. To enable a potentiometer to be connected to these
terminals, Parameter 9 must be set to 1, 2 or 3. The potentiometer
frequency control range is the range between minimum and maximum
drive frequency as set by Parameters 15, 16, 50, 51, 53 and/or 54. The
frequency resolution is 0.1 Hz up to 100 Hz, 0.2 Hz up to 200 Hz, and
0.5 Hz if over 200 Hz.
Terminal 1
Potentiometer High
Full CW or high side external potentiometer connection.
Terminal 2
Potentiometer Wiper
Wiper external potentiometer connection.
Terminal 3
Potentiometer Low
Full CCW or low side external potentiometer connection.
Terminals 3, 8, 11, and 17
Logic Common
These terminals are provided to terminate both minus and drive common
signals to the Control and Signal Wiring Terminal Block.
Terminals 4 and 3
0Ć5 or 0Ć10VĂDC
This terminal is provided to terminate a 0 to +5 or +10V DC speed
reference signal. The minus signal is terminated at Logic Common.
Parameter 9 enables the speed reference signal and selects either a 0-5V
input signal (when set to 1), or a 0-10V input signal (when set to 2).
Parameters 52, 53 and 54 sets the output signal to be either directly or
inversely proportional. The input impedance from Terminal 4 to logic
common is approximately 40k
Ω
. The range of frequency control is
between the minimum and maximum drive frequency settings or frequency
clamps as set by Parameters 15, 16, 50, 51, 53 and/or 54. The frequency
resolution is 0.1 Hz up to 100 Hz, 0.2 Hz up to 200 Hz, and 0.5 Hz if over
200 Hz.
