Frame 3 drives (firmware version 1.x) only:
Figure 72 - Dig In Status (216) Frame 3
On the Frame 3 drive, AC Line I/O Digital Input 1 is used for precharge
contactor feedback.
•
A 1 in bit 0 indicates that all of the precharge contactors are closed.
•
A 0 in bit 0 indicates that at least one of the contactors is open.
Also on the Frame 3 drive, bit 9 indicates that AC line rotation has been
determined, bit 8 indicates whether the rotation is ACB (not usable) or ABC
(usable), and bits 10...15 provide information about the internal state of the AC
line synchronization function of the AC Line I/O board. Bits 10...15 are for
engineering use only.
On the Frame 3 drive, AC Line I/O Digital Inputs 3 and 4 are used to select
measurements to be displayed on the optional input voltage and current meters,
as described in
Table 13 - AC Line I/O Digital Inputs 3 and 4 (Frame 3)
