4.3 Connections Summary—Motor
Amplifiers
The Prodigy/CME PC/104 card supports four methods of output to motor amplifiers, as described in the following
table:
In addition, each motor axis may have one, two, or three output phases associated with it. For DC brush motors, the
number of phases is one. For multi-phase motors such as brushless DC or microstepping motors, the number of
phases can be two or three, depending on the output waveform programmed into the Prodigy/CME PC/104 card.
For more information, see the
Magellan Motion Processor User’s Guide.
The following tables provide convenient summaries of amplifier connections for common configurations of motor
output method and motor type. These outputs should be connected from the designated connector pins to the
appropriate amplifier inputs. Note that the names of the pins will vary among amplifiers. Common names are shown.
4.3.1 DC Brush Motor Connections
To connect to DC Brush motors the GP Connectors (J5 &J6) are used.
* Names of amplifier connections vary. Common names are shown.
** Both the Magnitude and Sign connections are used if the Magellan’s PWM Sign Magnitude mode is selected. If PWM50/50 mode is
selected, then only the Magnitude connections are used.
4.3.2 Brushless DC Motor Connections
To connect to Brushless DC motors using internal commutation (provided by the Magellan Motion Processor), two
sinusoidal phase signals are driven per axis via the Option Connector (J9).
Motor Output
Method Signal Output
DAC Analog signals from the onboard D-A converters.
PWM sign-magnitude Pulse width modulated signals with separate magnitude and sign signals per output phase.
PWM 50/50 Pulse width modulated square-wave signals with a single PWM signal per output phase.
Pulse & Direction One signal representing pulse information, and a signal representing direction.
