ANAGEMENT
This chapter discusses the management of encoder errors, ASCII programming using CME 2,
clearing faults, and absolute position.
CME 2 uses ASCII variables to read status information and to configure absolute encoders. The
mapping of bits to function depends on the encoder type. For details pertaining to specific encoder
types see
Encoder Status Words, p. 40 and Encoder Option Words, p. 42 .
For a full list of parameters see the Copley Amplifier Parameter Dictionary. For detailed ASCII
programming (which includes error codes),
see the Copley ASCII Interface Programmer’s Guide.
