Digital Input Option Card
DI-08
7. Adjustment: There are no adjustments that need to be made to the DI-08 option; however, the drive will have to be
programmed for the input requirements of the peripheral device. See Table 4.
Important: For the digital reference to function properly, the drive needs to be programmed to use the digital
reference. This can be done in one of two ways:
a) If drive always uses the DI-08 speed reference:
Program b1-01 = “3” (Option PCB)
b) If the drive is using multi-function digital inputs to select multiple speed references:
1. Program b1-01 = “0”, “1”, or “2” (depends on required speed reference source).
2. H1-03 (or other input) = “2” (Option / Inverter Select).
3. Close terminal S5 (5 on the G5) on the drive’s control board to select the DI-08 digital reference.
8. Reinstall and secure the drive’s cover.
9. Place this instruction sheet with the drive’s technical manual.

--- SIGN signal: “Off” = Forward Direction Command
: “On” = Reverse Direction Command
* SET (load) signal is used to tell the drive to read the data. To set, close between TC-10 and TC-11 by the timing shown
in Figure 3.
