Electrical Interface
To ensure reliable encoding performance, the AEDT-9140
three channel encoder modules require 2.7 kΩ (± 10%)
pull-up resistors on output pins 2, 3, and 5 (Channels A, I
and B) as shown in Figure 3. These pull-up resistors should
Figure 3.
Customized Solutions
Customization of codewheel CPR is possible. It has to be
based on the encoder LPI table given below.

be located as close to the encoder module as possible
(within 4 feet). Each of the three encoder module outputs
can drive a single TTL load in this configuration.
CPR calculation formula:
CPR = LPI x 2 x S x ROP
Where:
CPR = Counts Per Revolution
LPI = Encoder LPI provided in the table
ROP = Encoder Optical Radius in mm
* Recommended maximum codewheel diameter should
not exceed 30mm.
Note: The customization of the codewheel method is valid from theoreti-
cal standpoint. However Avago strongly recommends a full character-
ization to be done to determine the actual performance of the encoder
with customized codewheel.
Characterization means validating the encoding performance (consist
of cycle error, pulse width error, logic state width error, phase error, po-
sition error & index pulse width, index channel rise and fall time over
the recommended operating conditions and recommended mounting
tolerances.
