3-14 PowerFlex 700S Control Wiring
Figure 3.4 TB2 - Row B (Bottom) Wiring Examples
Hard Enable Circuitry
The PowerFlex 700S provides a dedicated hardware enable input for
applications that require the drive to be disabled without software
interpretation.
Input/Output Connection Example Required Parameter Changes
Secondary Encoder Interface
- Supports 12V dc differential
encoders with internal power
supply.
5V dc differential encoders
require external power supply
and special jumper settings.
Refer to Auxiliary Power
Supply on page 3-15 for
external power supply and
jumper settings.
For 5V dc differential encoders
with internal power supply, set
Jumper J6 to positions T2 and
T3.
Secondary Encoder - using internal power supply Example: Using Encoder 1 for Primary Motor
Speed Feedback
• Set the value of Parameter 222 [Motor Fdbk
Sel] to a value of 1 - Encoder 1, so the drive will
use this encoder as the primary motor speed
feedback device
• Set the value of Parameter 242 [Encoder1 PPR]
to match the encoder’s resolution
Secondary Encoder - using external power supply
Auxiliary Output - Relay
contact output
Auxiliary Output, Used to Indicate Running Example: Using Auxiliary Output to Indicate
Running
• Link Parameter 155 [Logic Status], the source,
to Parameter 841 [Relay Out Data], the sink
• Set Parameter 842 [Relay Out Bit] to a value of
one, so that Parameter 155 [Logic Status] / bit 1
“Running” will control the output.
