KStep — 4-Axis Microstepper Amplifier for KFLOP

Click for large photo.

This ease-of-use also comes with high performance, high efficiency, and additional 12-24V isolated I/O expansion sufficent for most applications. Although it is possible to use third-party stepper or servo drives with our KFLOP controller, KStep provides complete connectivity with a single ribbon cable connection, easily mounts to KFLOP with standoffs, and gets the most out of our software. In addition, KStep's ultra low resistance MOSFETS eliminates the need for special cooling and heat sinking. This setup reduces cabling and wiring and puts everything you need into a nice footprint. KStep really is a culmination of many customer requirements in one expansion board.

KStep 4-Axis Microstepper Amplifier for KFLOP

KStep is a KFLOP expansion board designed specifically for plug-and-play stepper motor control. With only a motor power supply, stepper motors and the KFLOP+KStep you have all you need to start controlling 4 motors (or 8 with 2 KSteps).

Please view our on-line documentation for full details.

Example Applications:

Most anything using 200+W Steppers
CNC machining:

Mills
Lathes
Brakepresses
Grinders
Spinners
Routers
Saws

Robotics
Automation
Camera Control
Pick-and-place
Data Acquisition

Example Input/Outputs:

Size 23 Stepper Motors
Stepper Motors greater than 5A are ok, but current is limited at 5A which is generally not a problem
Simple sinking 24V Limit and Home Switches
Spindle controls with 0-10V analog input

Not to be used with:

Supply voltages lower than 12V and higher than 48V
