Hardware 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
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 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 1, so that
Parameter 155 [Logic Status], bit 1 “Running”
will control the output.
