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

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
[DigIn1 Sel] to a value of zero (0) 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
[DigIn1 Sel] to a value of zero (0)
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"
Using Relay Out to annunciate "drive running:"
• Link the status word to the relay control
Par 841 [Relay Out Data] (the destination) linked to
Par 155 [Logic Status] (the source)
• Set Par 842 [Relay Out Bit] to a value of 1, so that Par
155 [Logic Status], bit 1 [Running] will control the
output.
