Description
Five identical encoder inputs, each with complementary A, B and Z
channel inputs on a 9-pin female D-type connector
Up to five incremental encoders may be connected to NextMove BX
II
. The auxiliary (master)
encoder (X13) is labeled Aux Encoder . Each input channel enters an AM26LS32AM differential
line receiver with pull up resistors and terminators. Encoders must provide 5V single ended or
differential signals, or RS422/RS485 differential signals. The use of individually shielded
twisted pair cable is recommended. See section 4.4.1 for details of the encoder power supply.
