Check that the sequence of pins of different PG cards is consistent, and connect cables by referring to the table above.
Thank you for purchasing the SIN-COS photoelectric encoder developed
by Weton.
The SC53 SIN-COS photoelectric encoder produces sine waves. Through
the changes of sine and cosine waves, the subdivided voltage can be
obtained. Then, output signals of the encoder is subdivided as required to
improve resolution. The SC53 SIN-COS photoelectric encoder adopts the
new-type conical shaft and expanders for easy xture. This further simpli-
es the motor control system structure. The SC53 SIN-COS photoelectric
encoder is applicable to elevators, servos, machine tools, and automatic
control equipment. It is mainly applied to control systems of permanent
magnet synchronous elevators.
Before using the encoder, read this guide thoroughly.
