I/O Wiring Examples

Input/Output Connection Example
Sourcing Input - using internal power supply
Digital Inputs used for
enable and precharge
control.
Note:
24V DC Supply - Sourcing Input - using external power supply
supports only on-board
digital inputs. Do not use
for circuits outside the
drive.
Auxiliary Outputs - Digital Output 1 Indicating Alarm and Digital Output 2 Indicating
24V DC outputs 25 mA Fault - in sourcing configuration
maximum per output
This section provides basic information to wire the PowerFlex 700S.
Table K Digital Wiring Examples
The following definitions are used throughout this section:
Source
• Apply positive voltage through the device to the input or output.
• Connect the input or output common (return) directly to the power supply common.
Sink
• Apply the positive voltage directly to the input or output common (return).
• Connect the input or output to the power supply common through the device

Fixed - If this is not
used a jumper must be

If this is not used the drive must
be re-programmed or use a

Required Parameter Changes
Enable - In sinking configuration, this circuit must
connect to 24V DC power for 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
[DigIn 1 Sel] to a value of zero or replace the contact
shown with a jumper from Terminal 8 to Terminal 10.
If precharge is needed, in sinking configuration, this
circuit must connect to 24V DC power for drive to
.
complete the precharge cycle
Enable - In sourcing configuration, must connect to 24V
DC common for 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
[DigIn 1 Sel] to a value of zero
If precharge is needed, in sourcing configuration, must
connect to 24V DC common for drive to enter pre charge

Using DigOut 1 to annunciate an alarm:
• Link the status word to the output control
Par 843 [DigOut 1 Data] (the destination) linked to
Par 155 [Logic Status] (the source)
• Select which bit activated the output
Par 844 [DigOut] / 1 Bit = 8 "alarm"
