All microstepdrivers for steppermotors we sell have a current limitation by PWM ( Puls Width Modulation ). This means that the drivers don't need a large couling. Furthermore, all drivers have optocoupler inputs, so if a microstepdriver breaks down, the connected computer is protected. All microstepdrivers can be turned off ( idle ) by means of a switch, allowing the steppermotor to be turned by hand, or ( in case of an endswitch ) to protect the system by turning the microstepdriver and steppermotor off, no matter what the state of the computer is. Also, these microstepdrivers are completely build and tested. All wires are attached to the microstepdriver by means of connectors. These can be easy disconnected in case of a broken microstep driver. And all microstep-drivers can be used with free programs like Turbocnc ( dos ), Mach3 ( windows ), EMC ( Linux ), and all programms that use a step and direction signal. .

This is a simple and cheap microstepdriver. It has 1,2,4 or 8 microsteps. This means a hybride steppermotor ( most common type ) with 200 steps/revolution makes 200, 400, 800 or 1600 steps per revolution. Powersupply may be between 12 Vdc and 35 Vdc. Powersupply can also be delivered by the computer. Optocoupler input for step, direction and enable. Maximum stepfrequentie is 100 Khz. Current selectable between 0.4-2.5 Ampere. Very good steppermotor-driver for small cnc-machines, or for a beginner to start with cnc. This steppermotor-driver has a build-in protection against high temperatures.
This steppermotor microstepdriver may have a powersupply input between 20 Vdc and 50 Vdc. It has a maximum output current of 5.6 Ampere. It has an optocoupler input for step, direction and enable ( freerun ) and microsteps up to 25.600 step a revolution. It has a build in protection agains high temperatures and high voltages. It can supply microsteps to steppermotors of up to 12 Nm. Very powerful microstep driver.
This microstepdriver has a maximum powersupply input of 230 Vac ( can also used without a transformer, but that is NOT RECOMENDED ) and has a maximum output current of 7.8 Ampere. It has an optocoupler input for step, direction and enable ( freerun ) and microsteps up to 10.000 step a revolution. It has a build in protection agains high temperatures and high voltages. Also it has a build in fan. This microstepdriver is NOT for starters with cnc. It has the ability to output 300 Volt, and those can be lethal.
The SJ-030 is a small microstepdriver with a combined powersupply for both the logic and the steppermotor. The powersupply may be between 24 and 40 Vdc. The inputs are of the optocoupler type, so there doesn't have to be a problem with earth. The input it needs are step, direction and enable. The steppermotor takes a step if the stepinput goes from low to high. The motor takes then a step clockwise or counterclockwise depending on the state of the direction input. If the enable input is pulled low, the driver disables the motor, thus giving the oportunity to be turned by hand. The microsteps of the driver can be: 2, 5, 10, 20 of 40. With a hybridesteppingmotor with a normal step of 200 steps ( 1.8 degree ) this will be 400, 1000, 2000, 4000 of 8000 microstappen for one turn. The current can be set to : 0.5, 1.0, 1.3, 1.5, 1.7, 2.0, 2.4, 3.0 Ampere. the normal way of connecting this driver is through the printerport ( LPT ). The new type has a build-in cooling and a protection agains high temperature. There are seperate connectors for the motor, powersupply and the controlsignals.
This mikrostepdriver needs just a unrectified current, so no need for an expensive DC powersupply. A transformer with two output voltages ( or of couse two transformers ) is all that is needed. One voltage is used for the logic and may be between 16 and around 19 Vac. The other voltage may be between 40 and 65 Vac and is used for the powerpart to the steppingmotor. The advantage of this is the lack of influence of the powerstage on the logic. The inputs are of the optocoupler type, so no problem with earth. The input needed is step/direction and an enable. The motor takes a step if the step input goes from high to low. The input of the direction input decides which direction the motor turns. If the enable input is pulled low, the driver disables the motor, thus giving the oportunity to be turned by hand. The microsteps of the driver can be: 2, 5, 10, 20 of 40. With a hybridesteppingmotor with a normal step of 200 steps ( 1.8 degree ) this will be 400, 1000, 2000, 4000 of 8000 microstappen for one turn. The current can be set to : 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0 Ampere. the normal way of connecting this driver is through the printerport The driver has a build in fan, and is protected against high temperature.

Also it has a fault output, a relais which closes upon a fault. This can trigger an alarm.
