SB3000 Drive Configuration and Programming

VAR Feedback (Volts * Amps) Register

211/1211

The VAR Feedback register contains the volt-amperes reactive
(VARS) produced by the Rectifier in response to the reference in
register 103/1103. The value is scaled in VARS divided by 1000. For
example, 10,000 VARS (10 KVARS) is displayed as 10.

Sug. Var. Name:

Iq Feedback (Amps) Register

212/1212

The Iq Feedback register contains the Iq component of the current
feedback. Iq is the current that supplies the DC bus. The value is
normalized to the configured current limit parameter (i.e., 4095 =
current limit).

Id Feedback (Amps) Register

213/1213

The Id Feedback register contains the Id component of the current
feedback. Id is the reactive current component that can be used to
produce a leading power factor. The value is normalized to the
configured current limit parameter (i.e., 4095 = current limit).

User Analog Input Register

214/1214

The User Analog Input register contains the DC bus current as
measured from the Resolver Feedback connector on the Resolver &
Drive I/O module. It is scaled as follows:

Single Power Module:2047 counts = 641 Amps (319 counts / 100 amps)

Double Power Module:2047 counts = 1282 Amps (160 counts / 100 amps)

Triple Power Module:2047 counts = 1923 Amps (106 counts / 100 amps)

Selected Variable Register

219/1219

The Selected Variable register contains the value of the actual
variable that is selected for display on PMI meter port 4. This allows
monitoring of data in the UDC module that is normally only available
in the PMI rack.

Sug. Var. Name:

SEL_VAR%
