smoothing. For smooth following of complex contours, the CDS-3310 provides continuous feed of an
infinite number of linear segments (contour mode).
For synchronization with outside events, the CDS-3310 provides uncommitted I/O, including 8 digital
inputs, 10 digital outputs, 2 analog intputs (0-5V) and one analog output (-10V to 10V). When the
DB-28040 is added to the controller, the CDS-3310 has 8 analog inputs and an additional 40 digital
I/O. Dedicated TTL inputs are provided for forward and reverse limit switches, a home switch, and
abort.
Commands can be sent in either Binary or ASCII. Additional software is available for automatic-
tuning, trajectory viewing on a PC screen, and program development using many environments such as
Visual Basic, C, C++ etc. Drivers for DOS, Linux, QNX, Windows 3.1, 95, 98, 2000, ME, NT and XP
are available.
Amplifier Specifications
The CDS-3310 integrated amplifier is a brush/brushless trans-conductance PWM amplifier. The
amplifier operates in torque mode, and will output a motor current proportional to the command signal
input from the controller. For high current applications (near 7 amps continuous), the metal enclosure
should be mounted to metal backing to dissipate heat
*Note: *Do not "hot swap" the motor power connections. If the amp is enabled when the motor
connector is connected or disconnected, damage to the amplifier can occur. Galil recommends
powering the controller and amplifier down before changing the connector.
