3-6 Control Wiring for PowerFlex 700S Drives with Phase I Control
Input/Output Connection Example Required Parameter Changes
Sinking Precharge and Enable Inputs - using internal power
supply
Enable - In a sinking configuration, this circuit must
connect to a 24V dc return for the drive to run.
Precharge
Precharge control is used in common bus
configurations and is not required for AC fed drives.
If precharge control is not required, reprogram Par
838 [DigIn1 Sel] to a value of zero or replace the
contact shown with a jumper from terminal 8 to
terminal 11.
If precharge is needed, in sinking configuration, this
circuit must connect to a 24V dc return for the drive to
complete the precharge cycle.
Sinking Precharge and Enable Inputs - using external power
supply
Digital Outputs - 24V dc
outputs 25 mA maximum per
output.
Digital Output 1 Indicating Alarm and Digital Output 2
Indicating Fault - in sourcing configuration
Example: Using Digital Outputs 1 and 2 to
Annunciate Alarms and Faults
• Link Parameter 155 [Logic Status], the source, to
Parameter 843 [DigOut 1 Data], the sink
• Set Parameter 844 [DigOut 1 Bit] to a value of 8, so
that parameter 155 [Logic Status], bit 8 “Alarm” will
control the output
• Link Parameter 155 [Logic Status], the source, to
Parameter 845 [DigOut 2 Data], the sink
• Set Parameter 846 [DigOut 2 Bit] to a value of 7, so
that Parameter 155 [Logic Status], bit 7 “Faulted”
will control the output
Digital Output - 24V dc
output 25 mA maximum per
output.
If one output is configured in
sinking, the other output is not
available.
Digital Output 1 Indicating Alarm Fault - in sinking
configuration
Example: Using Digital Output 1 to Annunciate
Alarms
• Link Parameter 155 [Logic Status], the source, to
Parameter 843 [DigOut 1 Data], the sink
• Set Parameter 844 [DigOut 1 Bit] to a value of 8, so
that Parameter 155 [Logic Status], bit 8 “Alarm” will
control the output
