3.8 Control Circuit Wiring
■ Output Terminals
Table 3.6
lists the output terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
output.
Note: M ulti-function relay output terminals are rated at a minimum o f 10 mA. I f less than 10 mA is required, use the photocoupler
outputs (P1-C1, P2-C2). Using the wrong current output level may cause the output to malfunction when the terminal is activated.
