Introduction
The Galil CDS-3310 controller/drive system is a single-axis integrated Ethernet controller and
brush/brushless amplifier (18-72 VDC, 7 A continuous, 10 A peak) that can be used in one of several
ways, depending on how many total machine axes need to be controlled:
Machine
Axes
1
1.5
2 to 8
2 or more
Each CDS-3310 provides two communication channels: RS-232 (up to 19.2K Baud) and 10/100BaseT
Ethernet. The serial port may be replaced with a USB port as a factory option.
A 4Meg Flash EEPROM provides non-volatile memory for storing application programs, parameters,
arrays and firmware. New firmware revisions are easily upgraded in the field.
Designed to solve complex motion problems, the CDS-3310 can be used for applications involving
jogging, point-to-point positioning, electronic gearing to an encoder, multiple move sequences, and
contouring. The controller eliminates jerk by programmable acceleration and deceleration with profile
CDS-3310
Mode
The CDS-3310 is used by itself for single axis applications
The CDS-3310 is used by itself in conjunction with its second
encoder input for gearing, backlash compensation, or reading a hand
wheel.
The CDS-3310 is used in conjunction with up to 7 other CDS-
3310s. In this "distributed" mode of operation, programming is
simplified because multiple controllers behave as a single multi-axis
controller. Only the master controller requires an application
program and/or the host PC communicates only with the master
controller.
The CDS-3310 is used in conjunction with one or more Galil DMC-
14x5, 21x2/3, 22x0 or CDS-3310 Ethernet controllers. In this mode
of operation, each controller must contain it's own application
program and/or a host PC must communicate with each controller
individually. The number of controllers (and axes) that can be
linked together via Ethernet is only limited by the number of IP
addressed available. Controllers communicate with each other via
the SA command. Groups of axes that are "tightly coupled" via
vector mode (VM), linear interpolation (LM), multi-axis gearing
(GA), or multi-axis camming (EA) must be grouped onto multi-axis
controllers.
