PC Serial Port Stepper Motor Interface Card

PC Serial Port Stepper Motor Interface Card
NOW MUCH FASTER - Up to 6.3kHz Stepping Rates
SIMULTANEOUS MOTOR CONTROL ADDED
Connects to the PC serial port and provides an easy to use interface for connecting and controlling stepper motors by your PC. 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. A free PC program (source code in VB is included) is provided so that you can execute a number of commands and repeat the process

Examples of the commands are

    @01 AMOV 1000 2000 n 4000 do an absolute move of stepper 1,2 and 4 to positions 1000, 2000 and 4000
    @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
    @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. 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.

Serial Bipolar Stepper Motor Driver

CLOSEOUT ITEM - WHILE STOCK LASTS.

Serial Bipolar Stepper Motor Driver
Is a combination of our popular KT5190 Serial Stepper Controller and the KT-5196 Bipolar Stepper Motor Driver.
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
    @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.

The new card features
- accepts the same serial ASCII commands as the KT-5190 to drive the motor eg @01 RMOV 10000
- accelerate and decelerate motors
- control up to 4 KT-5197's from the one RS232 serial port
- accepts a 0-5V signal to control the speed of the stepper motor.
- a double sided PCB (more reliable and no links to solder).
- screw Terminals for all inputs, power connections and motor connections.
- Full and Half Step (less resonance problems) operation
- Step and Direction Input.
- an enable input which will remove all power to the motor

The KT5197 is able to drive 4 wire (and 6 or 8 wire) bipolar stepper motors at up to 8 amps
Please note there is not inbuilt current limiting for the coil currents

Dual Bidirectional DC Motor Speed Controller

NOTE: Maglev fan pictured is not included.

Description:This Motor Speed Controller allows a user to control the speed of up to two DC Motors independently, using an analog 0-5V signal, potentiometers, serial port of a PC or 1-2mS RC Pulse.

Modes of Operation: The BB250 (KTA-198) can be operated in serial, analog or pulse mode. In analog and pulse modes each motor can be operated in unidirectional mode with the 0-5V analog input (or 1-2mS pulse) giving 0-100% PWM and a digital input for direction selection, or in bidirectional mode where the analog or pulse input is responsible for both direction and speed selection. In bidirectional mode 2.5V (or 1.5mS pulse) will give 0% PWM duty, increasing voltage from 2.5V to 5V (or pulses from 1.5 to 2mS) will increase the PWM duty from 0-100% and turn the motor in one direction. Decreasing the voltage from 2.5V to 0V (or pulses from 1.5 to 1mS) will increase the PWM duty from 0-100% and turn the motor in the other direction.

The PWM frequency can be set by a serially command to 10KHz, 1.25KHz and 156Hz.

The maximum voltage available to run the motor is 50VDC.Current: The IRFZ44 MOSFET can handle 49A; the IRF4905 can handle 74A. However the PCB tracks that run from the MOSFET pins to the screw terminal block can only handle around 10A. When running the motor check the temperature of the MOSFETs to see if heatsinks are required.
