Operation
2.4.4 Pulse and Direction
For pulse & direction motors these signals provide a stream of pulse and direction data, compatible
with a wide variety of off-the-shelf step motor amplifiers. These signals are directly generated by the
Navigator motion processor. For more information on output waveforms, pulse rates, and related
information, see Navigator Motion Processor User’s Guide.
These signals are named pulse1-4, direction1-4.
The default value, upon powerup, for all pulse & direction output signals is high.
Connections & associated signals
This group of signals are direct single-signal digital outputs. There are no associated connections that
need to be made for these signals to function properly, however one or more of the digital grounds
must be connected.
For a complete description of the pinout connections to/from the card, see section 5, Navigator-PC/104
Electrical Reference, page 55.
2.4.5 PWM Out
For servo or microstepping motors these signals provide PWM (pulse width modulated) motor com-
mand signals when the motor output mode is set to PWMSignMagnitude or PWM5050Magnitude. See
the Navigator Motion Processor User’s Guide for complete information. The number of signals per axis
varies depending on the motor type being connected to, the number of phases that the motor has, and
the motor drive method (sign/magnitude or 50/50). Section 5, Navigator-PC/104 Electrical Reference,
page 55, has complete connection tables for various motor configurations.
These signals are named PWMMag1A-4C (12 signals) and PWMSign1A-4B (8 signals).

2.4.6 Motor Command
For servo or microstepping motors, these signals contain the analog motor command when the motor
output mode is set to DAC (digital to analog converter). These signals vary between -10V and +10V. See
Navigator Motion Processor User’s Guide for more information. The number of signals per axis varies
depending on the motor type being connected to.
These signals are named DAC1A - DAC4B (4 signals)
Connections & associated signals
For analog voltages to be output correctly, AGND (motor command ground) must be connected.
