Optional Bandwidth & Tracking Rate Component Set-Up
On Evaluation Board:
A second set of bandwidth and Tracking Rate Components can be
customized by populating socket S3, using the supplied 8 pin component
carrier (See Figure 4) and setting the shift switch “SW1-S1” to the “On”
position.
These components can be calculated using the preferred component
calculation software program provided on the Synchro/Resolver products
software CD-ROM, under the converter product listing or can be downloaded
from
.
Note: R clock and R set evaluation board resistors are not adjusted per the
component calculation software program. These resistors are pre-set for a
frequency range of 1 to 5Khz. For other frequency ranges see “table 3, carrier
frequency range” for instructions to adjust R28 & R29 “R clock and R set
parallel resistors”.
The preset velocity resistor R9 is 357k
Ω
, which will result in a tracking rate of
2.5rps in 16-bit resolution. Higher tracking rates can be obtained by reducing
the value of R9. The RV position on the component carrier “S3” (See Figure
4) is in parallel with R9 and can be used to scale the velocity resistor value.

To operate the evaluation card in dual Bandwidth mode:
1) Remove TB2-J3 and install TB2-J4.
(This puts –5Vdc to the
Up
/ Dn digital input). Use the Shift digital
input SW1-1 to control selection of bandwidths.
2) Shift = SW1-1 off, logic 1 to select Vel 1 components
3) Shift = SW1-1 on, logic 0 to select Vel 2 components
(See the digital input control Table 4 for details).
