2. Encoder internal circuit
Item Pin No. Signal
ENC1A+ ENC1A+ Encoder 1A+ input
ENC1A- ENC1A- Encoder 1 A- input
ENC1B+ ENC1B+ Encoder 1 B+ input
ENC1B- ENC1B- Encoder 1 B- input
ENC2A+ ENC2A+ Encoder 2 A+ input
ENC2A- ENC2A- Encoder 2 A- input
ENC2B+ ENC2B+ Encoder 2 B+ input
ENC2B- ENC2B- Encoder 2 B- input
* Note1
Wiring of encoder 1 is example about 5V voltage output type (open collector). When using 12V, 24V type MPG,
change the input voltage from 5V to 12V or 24V and in case of 12V, connect 910Ω resistor to ENC1 A+(pin 1),
ENC1 B+ (pin3), in case of 24V, 2.4㏀ resistor, before connecting the power source (adding PULL-UP resistor is
needed)
* Note2
Wiring of encoder 2 is example about 5V voltage output type (line driver)
This describes the internal circuit of the module when connecting the encoder.
