Control Wiring - Analog Signal Follower
Model
You can control the output frequency of the
controller via the Control Terminal Block (TB3)
using a remote potentiometer, a –10 to +10 VDC
analog input, a 4–20mA analog input, or P58 –
[Internal Frequency].
Note: Only one
frequency source may be connected at a time. If
the frequency reference potentiometer and the
4–20 mA reference are connected at the same
time, an undetermined frequency reference will
result. If the –10 to +10 VDC analog input is not
used, it should be tied to terminal block common
terminal 7 to improve noise immunity. Refer to
Chapter 5, parameters P58–P60 for factory
default settings.
À Control signal cable length is highly dependent on
electrical environment and installation practices. To
improve noise immunity the control terminal block
common must be connected to earth ground.
Consult factory for longer control signal cable length
applications.

Control Wiring Requirements
D run all signal wiring in either a shielded
cable, or a separate steel conduit.
D only connect shield wire at control terminal
block common terminals 3 and 7 .
D do not exceed control wiring length of 15
meters (50 feet).
À
D use Belden 8760(or equivalent) – 18AWG
(0.750mm 2 ), twisted pair, shielded or 3
conductor.
Control Wiring - Preset Speed Model
You can control the output frequency of the
controller via contact closure input to SW1,
SW2, and SW3. A program keypad module is
required to change the factory default settings.
Refer to Chapter 5, parameters 61–70 for the
eight preset frequency factory default settings
and switch configurations.
ATTENTION: The controller is
supplied with an internal 12V
supply. Dry contacts or open
collectors are required for discrete
control inputs. If an external
voltage is applied, component
failure could occur.
Note: Refer to the diagrams on the following
pages for control wiring information.
