Rockwell Automation 1395 Digital Reference Adapter for RTP Applications - Manual (Page 14)

Publication 1395-RTP-5.2 - September 1997
2-2 Hardware Description
Digital Reference Input The Digital Reference Adapter Board contains one digital reference
input which produces a digital speed reference command for the
Drive which is proportional to the press speed of the RTP Unwind
Drive application. The Adapter Board is set up for the line speed
encoder input signal to be single channel, single edge, and is
configurable for two edge or quadrature. Only one of the edges, either
the rising edge or the falling edge is used by the counting logic by
default. The hardware is configured for 5 volt signal inputs with the
jumpers J6 and J7 in the 1-2 position. Position 2-3 is for a 12 volt
signal input. Connector J2 is used to make the interconnection for the
digital reference encoder inputs between the Adapter Board and the
Terminal Block, TB-3, which is used to make the following external
connections.
• J2-18 to TB3-26 Digital Reference Encoder Input NENCB1
• J2-17 to TB3-25 Digital Reference Encoder Input ENCB1
• J2-20 to TB3-24 Digital Reference Encoder Input NENCA1
• J2-19 to TB3-23 Digital Reference Encoder Input ENCA1
Only channel A is used (ie. TB3-23 & TB3-24).
