◆ Sinking/Sourcing Mode for Digital Inputs (CIMR-UA/UD/UT)
Set jumper S3 to select between sinking/sourcing mode, and internal or external power supply. Signal levels are the same
for terminals S1 through S8 and the safety inputs. The drive is preset to sinking mode.
NOTICE: An external power supply cannot be used in sink mode (+24 V common) and an internal power supply cannot be used in
source mode (0 V common). Refer to Control I/O Connections on page 110 for more information.

■ Sink Mode (0 V Common), Internal Power Supply
When controlling the digital inputs by NPN transistors (0 V common/sinking mode) or contacts using the drive internal
power supply, position the jumper S3 for sinking as shown in Figure 3.49.

■ Source Mode (+24 V Common), Internal Power Supply
When controlling digital inputs by PNP transistors (+24 V common/sourcing mode) or contact inputs using the drive
internal power supply, set jumper S3 for sourcing as shown in Figure 3.50.
