r.030 Digital Input Configuration

(Continued)

Figure 4.4 displays the options for selecting the speed reference when the RMI board
is used. Note that even with the additional options for controlling the MOP and Preset
Speeds, there is still only one MOP and there are still only eight preset speeds for
selection.

The shaded areas in figure 4.4 show the additional speed reference options when the
RMI board is installed in the drive.

Note that when P.000 = LOCL (0) and AUTO is selected, RMI digital input 1 (DIGIN 1)
is used to choose between the additional speed reference selected by P.008 and that
selected by r.030.

The digital inputs are read every RMI scan (1.0 ms). The RMI board requires the input
to be in the same state for 3 ms before a change in state is updated to the regulator.

For more information on digital input configuration, see the appropriate appendix in
the drive software instruction manual.

The selections shown in table 4.3 are described below.

Reference 1 / 2

DIGIN 1 is used to switch the RMI speed reference between the drive's terminal strip
inputs (Reference 1) and the RMI inputs (Reference 2).

If DIGIN 1 is off, the speed reference source is selected by parameter P.008.

If DIGIN 1 is on, the speed reference source is selected by parameter r.030 (see
table 4.3).

Analog / Freq

DIGIN 2 can be used to switch between the RMI analog input and the RMI frequency
input as the reference signal. Refer to figure 4.4.

If r.030 = 0 or 1 and DIGIN 2 is off, the RMI analog reference input (terminals 62, 63,
64) is used.

If r.030 = 0 or 1 and DIGIN 2 is on, the RMI frequency reference input (terminals 69,
64) is used.

If r.030

0 or 1, the input defaults to the RMI analog reference input (terminals 62, 63, 64).

Aux Input 1

DIGIN 4 can be programmed as an auxiliary input (Aux Input 1) by setting r.030 = 0, 2,
4, or 6. This auxiliary input can be used to turn any digital output or relay output on
and off with an on-delay or an off-delay using the corresponding time delay parameter
(r.040 through r.046).

If r.030 = 0, 2, 4, or 6 and DIGIN 4 is on, the Aux Input 1 function is enabled to control
the selected digital output or relay output.

If r.030 = 1, 3, 5, 7, or 8, the Aux Input 1 function is always off.
