Connecting the Stage Chapter 6
Sine/Cos Encoder Output
Signals
Use the following information to connect a stage with a Sine/Cosine Encoder
option to a drive or controller that processes sine/cosine position feedback.
The sine/cos encoder amplitude is 0.90V p-p minimum up to 2 meters per
second. 0.60V p-p up to 4 meters per second.
