24 Vdc, 8 mA
Use the wire link between terminals SC and SN or SC and SP to select
between sinking, sourcing mode, and the power supply.
–
24 Vdc power supply for digital inputs, 150 mA max (if no digital
input option DI-A3 is used)
Never short terminals SP and SN as doing so will damage the drive.
24 Vdc, 8 mA
One or both open: Drive output disabled
Both closed: Normal operation
Internal impedance: 3.3 kΩ
Off time of at least 1 ms
Disconnect the wire jumpers shorting terminals H1, H2, and HC to
use the Safe Disable inputs. Set the S3 jumper to select between
sinking, sourcing mode, and the power supply.
