Run/Stop and Frequency Reference
The Run/Stop and Frequency Reference commands can originate from:
Serial communication (Built-in Modbus: Keypad or R+/-, S+/- Terminals)
Keypad (Digital Operator)
Terminal Strip
Option Card
Parameter B1-01 (Run/Stop Method Selection) allows the selection of the origin of the Run/Stop command. Parameter B1-02 (Reference
Selection) allows the selection of the origin of the Frequency Reference command. The Run/Stop and Frequency Reference commands may
have different origins.
For example, the Run/Stop command may be set to Terminals (B1-01=1) while the Frequency Reference command may be set to Serial
Communication (B1-02=2).
