8 SBL23xx Motor Controller Datasheet Version 1.2 March 27, 2018
Connection to Analog Sin/Cos Absolute Encoder
The SBL23xx has four high-speed analog inputs that can be used to capture absolute an-
gle position from angular sensors with sin/cos voltage outputs. The signal must be 0-5V
max with the 0 at 2.500V.
Table 3, below, shows the signals assignment on the 25-pin connector.

Sin2 24 ANA7/ASIN2
Cos2 12 ANA8/ACOS2
Commands and I/O Connections
Connection to RC Radios, Microcomputers, Joysticks and other low current sensors and
actuators are done via the 25-pin connector. The functions of many pins vary depending on
controller model and user configuration. Pin assignments can be found in Table 4, below.
