Stepper Motor Controllers

KT-5193 Modbus Programmable Stepper Motor Controller
Based on the Serial Stepper Motor
Controller, the introduction of a more powerful microcontroller has
allowed us to produce a standalone 4 axis stepper motor controller which
can be programmed via a PC using supplied software or alternatively
controlled via a PLC to free the PLC from complex stepper motor control
routines. Up to 4 cards can be controlled from a PLC using the Modbus
protocol.

Up to 120
instructions can be programmed into the controller for 1 motor, 80
instructions for 2, 60 instructions for 3 and 50 instructions for 4
motors. Instructions are save in EEPROM and are retained through power
loss. Just program once and then let it go.

Ideal for repetitive
process tasks involving stepper motors, the unit provides 8 digital
outputs which can be used as the direction and step signals. The outputs
can also be used as general purpose digital
outputs when not being used for motor control and the 4 digital inputs can
be used for limit switches or program control.

KT-5190 PC Serial Port Stepper Motor
Interface Card
Connects to the PC serial port and provides an
easy to use interface for connecting and controlling stepper motors by
your PC. You can connect up to four KT-5191 Bipolar Chopper Drive,
KT5158 Bipolar Stepper Motor Drivers (See Below) or KT5179 Unipolar
Stepper Motor Drivers to the card using their step and direction
signals. You can multidrop up to 4 interface cards off the 1 RS232
serial line so you can control up to a total of 16 stepper motors.

You simply write ascii commands through the PC's serial port to the
card to control each of the stepper motors

Examples of the commands are

@01 AMOV 2000  do an absolute move of stepper
1 to position 2000
@02 RMOV -400  do a
relative move of stepper 2 400 steps backwards
@03
POSN 10000   indicate stepper 3 is at position
1000
@02 RATE 20 stepper 2 will move a step each
20msec
@04 STOP  stop stepper
4
@01 STAT   card sends the status of
motors 1 to 4 whether they are moving or not and status of limit
switches.

Positions can be between -99999999 and 99999999 steps. Stepping rates
are from 1 to 65535 millisecs. The user can also set the acceleration and
deceleration rates when starting and ending a sequence of steps. Limit
switch inputs are available for each of the motors to prevent motors
moving out of range.
New Feature:
Two new commands can turn on and off a direction signal on the
board for a specified time. For example the user could control two stepper
motors  for a telescope and using the commands switch on and off a
relay for a specified time to operate a camera shutter.

KT-5192 Parallel
Port Interface Card
Kit
Our
Parallel Port Relay card allows you to control stepper motor operations
from your parallel port. It uses a 74HC245 buffer IC to provide protection
for your PC’s parallel port and provide enough current drive for turning
on and off opto-isolator inputs. Can be connected to our KT5191, KT5158
and KT5179 stepper motor driver cards. Fitted with screw terminals it
allows for 4 Clock signals, 4 Direction Signals and 4 Limit or Emergency
Switches Terminals. Perfect for a 3 axis or 4 axis CNC machine. Pin outs
are suitable for most desk top CNC packages.
You can also use it in other
applications for I/O control from your parallel port

KT-5191 Bipolar Chopper Stepper Motor Driver
Kit
Our new bipolar chopper drive allows you to get better
performance from your stepper motor.
It uses a dual full bridge motor
driver based on SGS Thompson chips L297 & L298. Motor current for each
phase is set using an on-board potentiometer and the controller is capable
of
handling motor winding currents of up to 2 Amps per phase.
It
operates from a DC supply voltage of 9-36V. The drive provides all basic
motor controls, including full or half stepping of bipolar steppers and
direction control. Works with our range of large bipolar stepper motors MO-101,
MO-102 and MO-103
All signals (Step, Direction, Enable) can be
interfaced to external logic or a microcontroller. You can easily control
the motor from your computer's parallel port or our serial stepper
controller card!
This controller is perfect for desktop CNC
applications.

KT-5158 Bipolar Stepper Motor
Driver
Simple circuit to drive 4 wire (and 6 or 8 wire)
bipolar stepper motors. Motor control is via externally supplied 5V levels
for stepping and direction control. Both the STEP and DIRECTION inputs are
opto-isolated making it ideal for use with a PC running suitable software.
Uses IRFZ44 and MTP2955 MOSFETs to drive the motors at currents up to 6A.

Supply Required: 8-30V DC.

PCB: 75x85mm.

A CD containing a visual basic program
and source code which controls up to 4 motors from a parallel
port is included. Can be used with or without our parallel
interface card KT-5192. For those using the source code a copy of the
activeX component RS Timer (from  http://www.elprogramari.com/ ) is included if
fast speeds of the stepper motors are required.

KT-5179 Unipolar Stepper Motor
Driver
Standard circuit to drive 5, 6 or 8 wire unipolar
stepper motors. Can be operated in free-standing (internal oscillator) or
PC-controlled (direction, step) mode. Uses IRFZ44 power MOSFETs to drive
the motors. These MOSFETs have a low on resistance and can carry 6A each
without needing a heatsink. Uses
discreete logic ICs: 4013, 4030, 4093. Separate supply voltage for kit and
motors if required.

Up to six driver boards (for controlling 6 motors) can be connected to
a single PC parallel port. Full operational details provided (see
documentation link below). Screw terminal blocks and solder pins for
connections.
Note: There was a schematic error in the original Kit 179
documentation. The current documentation is now correct. Also the output
terminals on the PCB overlay are mislabelled - get the corrected overlay
here. The overlay will be fixed in the next run of PCBs.

A
CD containing a visual basic program and source code which
controls up to 4 motors from a parallel port is included. Can be used with
or without our parallel interface card KT-5192. For those using the source
code a copy of the activeX component RS Timer (from  http://www.elprogramari.com/ ) is included if
