3.9 Control Circuit Wiring
u Control Circuit Connection Diagram
Refer to Figure 3.1 on page 57 when wiring terminals on the drive control circuit.
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 M4, MD to MF), multi-function analog inputs (A1 to A3), and multi-function analog monitor outputs (FM, AM). The
default setting is listed next to each terminal in Figure 3.1 on page 57 .
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! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before starting test run. Setting parameter
A1-03 may change the I/O terminal function automatically from the factory setting. Failure to comply may result in death or serious injury.
n Input Terminals
Table 3.7 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function input.
