4. Product Function and Usage
The series of product have eight connection pins. Including phase A, B, C positive and
differential signals, and encoder power positive & ground.
4.1 Installation and Power Connection
Encoder must be properly and securely mounted, typically utilizing the treaded holes in the
motor end cover to connect with the motor, in special cases could also use adhesive for
connection. It will be recommended that encoder installed by manufacturer. If customer need
to install by themselves, then please be cautious and better contact manufacturer for
guidance. Meanwhile the encoder shall be installed in the good ventilated environments for
good thermal dissipation.
Connection of encoder to controller shall be strictly according to pin functions. Wrong
connection could lead to abnormal of encoder or even damage the encoder electronics.
4.2 Resolution Description
Resolution of the encoder series, also PPR specs, is the number of pules generated when
encoder disc rotate for one revolution. There are 32, 64, 128, 256, 512 and 1024 PPRs. Relative
Max. working frequency is 20, 40, 100, 180, 360 and 512 KHz.
The standard product is with differential signal output. Differential signal output model could
be used to achieve better system reliability.
