u Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S8), multi-function digital
outputs (M1 to M6), multi-function analog inputs (A1 to A3), and multi-function analog monitor output (FM, AM). The
default setting is listed next to each terminal in Figure 3.1 on page 46.
WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive
with untested control circuits could result in death or serious injury.
n Input Terminals
Table 3.6 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
input.

Safe Disable
Inputs
H1
Safe Disable input 1
24 Vdc, 8 mA
One or both open: Output disabled
Both closed: Normal operation
Internal impedance: 3.3 kΩ

Disconnect the wire jumpers shorting terminals H1, H2, and HC to use the Safe
Disable inputs. Set the jumper S3 to select between sinking, sourcing mode, and the
power supply as explained in Sinking/Sourcing Mode Selection for Safe Disable
Inputs on page 65.
