Control Circuit Wiring
♦ Control Circuit Connection Diagram
Refer to Standard Connection Diagram on page 46
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 (S3 to S8), multi-function digital
outputs (M1 to M6), multi-function photocoupler outputs (P1-C1, P2-C2), multi-function analog inputs (A1, A2), and
multi-function analog monitor output (FM, AM). The default setting is listed next to each terminal in
Figure 3.1
