Operation

2.7.4.1

Both single-ended and differential line driver versions of these signals are output from the Prodigy/CME PC/104

card. There are no associated connections required for these signals to function properly, however, one or more of the

digital grounds must be connected. See Chapter 4, Electrical Reference, on page 69 for a complete description of the

pinout connections to and from the card.

2.7.5

For DC brush, brushless DC or microstepping motors, these signals provide PWM (pulse width modulated) motor

command signals when the motor output mode is set to

number of signals per axis varies, depending on factors such as the motor type, the number of phases of the motor,

and the motor drive method (sign/magnitude or 50/50). See Chapter 4, Electrical Reference, on page 69 for complete

connection tables for various motor configurations.

These signals are named

2.7.5.1

These signals are generated by the Magellan Motion Processor. There are no associated connections required for

these signals to function properly, however, one or more of the digital grounds must be connected. See Chapter 4,

Electrical Reference, on page 69 for a complete description of the pinout connections to and from the card.

2.7.6

For DC brush, brushless DC or microstepping motors, this is the analog motor command when the motor output

mode is set to DAC Offset Binary (digital-to-analog converter). These signals are named

and vary between -10V and +10V. The number of signals per axis depends upon the motor type. See Section 4.5,

"Environmental and Electrical Ratings," on page 85 and the Magellan Motion Processor User's Guide for more information.

2.7.6.1

For analog voltages to be output correctly,

PMD provides software libraries in C/C++ as well as Visual Basic to access all of the functions provided by the

Prodigy/CME PC/104 cards. In addition, a special library of commands is used to access Magellan Motion Processor

functions called VB-Motion, and C-Motion.

The Prodigy/CME Programmer's Reference, in addition to providing detailed format and function descriptions of the PRP

messages associated with the Prodigy/CME PC/104 cards, also provides the equivalent C and Visual Basic library

calls. There is often, but not always, a direct correspondence between PRP messages and C language software

commands as they will be used for user application code to be executed in the host controller, or in the C-Motion

Engine.
