Press Release Summary:
Exp70-Q1 quadrature encoder input module for 1- and 2-axis RMC70 Series Motion Controllers includes A and B quadrature inputs plus one 12-24 Vdc high speed registration input. Single channel, Â½ axis, position or velocity reference input enhances RMC70 for geared applications. Up to 32 units can be daisy-chained for gearing up to 64 axes. Module has bi-color status LED to indicate proper functioning and fault states.
Original Press Release:
DELTA "Gears" Expansion Module for Encoder Reference Input
April 13, 2006 - Vancouver, WA - Delta Computer Systems, Inc. announces a new Exp70-Q1
quadrature encoder input module for the one- and two-axis RMC70 Series Motion Controllers. This
single channel, ½ axis, position or velocity reference input enhances the RMC70 Series for
The Exp70-Q1 includes A and B quadrature inputs plus one 12-24VDC high speed registration
input. The RS422 differential quadrature inputs have selectable termination allowing up to 32
Exp70-Q1's to be daisy-chained for gearing up to 64 axes. All inputs have galvanic isolation.
The Exp70-Q1 quadrature reference module has a bi-color status LED with solid green indicating
proper functioning and red flashing indicating a fault condition. An amber LED indicates that the
registration input is active.
Fault detection, such as a broken A or B wire fault, is indicated by A and B wire break status bits in
the RMC70Tools software.
Up to four field changeable expansion modules of various types, including discrete I/O and analog
inputs, can be mounted on the side of the versatile RMC70 Motion Controller base module adding
extra functionality in electric, hydraulic and pneumatic servo motion control applications.
"The addition of the Exp70-Q1 expansion module provides an easy-to-use, flexible and cost effective
benefit for customers with low axis count or distributed linear and rotary applications." stated Steve
Nylund, Delta CEO. "For example, a common master quadrature encoder signal can be used to
gear multiple RMC70 Motion Controllers. "Nylund added.
