OVERVIEW
The CCB-25 is a low cost driver and smart
controller board suitable for operating small
stepper motors. It utilizes a flexible phase
sequence generator and unipolar power
drivers with ratings up to 3 amps per phase.
This all-in-one package is designed for OEM
applications using high volume production
linear actuators, rotary steppers and solenoid
or valve drivers. Built in phase step
sequences include Full, Half, and Wave
drives. A custom, user sequence capability
provides a means to sequence 8 states with up
to four devices.
The CCB-25 has an instruction set of over 30
commands that include loop on port, count
delays, and set/clear ports. In addition to 6
general-purpose ports, jog, limit and home
sensor inputs are also available.
The CCB-25 has several features not found in
other
controllers. In addition to the
customizable phase sequence, auxiliary step
pulse/direction inputs allow motion
generation via external pulse sources, with
limit switch protection and position counter
tracking.
For evaluation and medium volume
production, a companion “mini-mother”
board simplifies product interface. The dual
axis board has an RS-232 interface,
expandable for multiple axes. The
communication, power and I.O. signal
connectors provide for real-world interface.

TERMINAL INTERFACE
By using a simple RS-232 buffer, motion
sequences can be programmed from a
standard terminal or host PC. Command lines
consist of an ASCII character followed by a
number. The input line editor provides a userfriendly
interface. The DCMB (mother
board) includes an RS-232 interface.
PARTY LINE MODE
“Party Line” communication protocol is
required when a host computer application,
other then “dumb” terminal mode, is used.
This protocol greatly reduces communication
time and supports between 1 and 60 axes of
motion connected in parallel from a single
serial port.
NON-VOLATILE MEMORY
2k byte of non-volatile memory is available
via the Go command to store user programs
for future execution. Any number of
programs may co-exist, limited only by the
available memory space. By implementing
non-volatile memory, all parameters, such as
initial velocity, ramp, step mode, etc., may be
set as defaults then modified "on the fly"
during program execution.
