5-6 PLC Ladder Logic Programming
The portion of the program shown in Figure 5.4 displays the status of
the drive by reading the status information in the drive’s logic status
word and displaying it at the operator’s station.

Drive Status Display logic
The portion of the program shown in Figure 5.5 moves a Frequency
Reference to the drive. The word is scaled 0 to 32767 equals 0 to
maximum frequency. Scaling may differ for other products.

Drive Frequency Reference
The portion of the program shown in Figure 5.6 moves the drive’s
Frequency Feedback from the drive’s feedback word to the PLC. The
word is scaled 0 to 32767 equals 0 to maximum frequency. This
scaling may differ on other SCANport products.

Frequency Reference
This rung moves a frequency reference from N7:0 to the drive's FREQUENCY REFERENCE input word at N13:1.
Frequency scaling on the 1305 AC Drive is such that 0 - 32767 = zero - max frequency.
