3.9 Control Circuit Wiring
Control Circuit Connection Diagram
Refer to Standard Connection Diagram on page 60 when wiring terminals on the drive’s control circuit.
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 61.
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.
WARNING! Confirm the drive I/O signals and external sequence before starting test run. Setting parameter A1-06 may change the I/O
terminal function automatically from the factory setting. Refer to Application Selection on page 114. Failure to comply may result in
death or serious injury.
Input Terminals
Table 3.7 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
input.

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 as explained in Sinking/Sourcing Mode Selection for Safe Disable
Inputs on page 88.
