Operation Method and Frequency Reference
The Run/Stop and Frequency Reference commands can originate from serial communication, the operator keypad, external terminals, or an
option card. Parameter b1-01 (Operation 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 External Terminals (b1-01 = 1) while the Frequency
Reference command may be set Serial Communications (b1-02=2).
