GPD315 Communication Parameters
Run/Stop and Frequency Selection
The run/stop and frequency reference commands can originate from serial communication, the
digital operator, or the external terminals. The origin of the run/stop command does not have to
be the same as the origin of the frequency reference command. Parameter n003 (Operation
Method Selection) allows you to set up the origin of the run/stop commands. Parameter n004
(Reference Selection) allows you to set up the origin of the frequency reference command. The
charts below illustrate the possible run/stop and frequency reference selections.
