Dynomotion: Servo Drive I/O Kanalog

Kanalog is an expansion board for KFLOP that adds six types of powerful I/O - enough to control a complete system such as a mill or router, in many cases. It's these capabilities that make Kanalog our most popular expansion board for KFLOP.

After examining a number of typical CNC control applications, Kanalog was designed to meet the requirements that we encountered the most. Many systems with obsolete controls can be retrofitted with the state-of-the-art trajectory control and user interface provided by the KFLOP+Kanalog combo with minimal cost while taking advantage of existing amplifiers and motors.

In addition, Kanalog was designed specifically to interface to analog servo drives with +/-10V analog input commands for either torque or velocity. It provides an interface for differential encoder inputs, optical inputs (typically home/limits), optical outputs (typically amplifier enablers, spindle control, coolant, etc...). Relay Outputs, and Digital IO.

Kanalog easily connects to the KFLOP (see pictures) and comes connected when purchased together. Only two simple connectors and four screws are required to mount the KFLOP onto the Kanalog expansion board.

Once connected, Kanalog uses the +5V it receives from KFLOP to generate +/- 15V on-board so that no other power supply is required. Kanalog's footprint with 112 screw terminals, which are pluggable, make wiring easy.

This KFLOP+Kanalog combo provides the most compact, low-cost, high-performance control package available. Unlike other systems with PWM or Step/Dir to Analog circuits, Kanalog includes true digital to analog converters with low ripple and fast response.

Kanalog is the most popular of the KFLOP expansion boards for its capability in incorporating the needs of a complete system. Those who are retrofitting mills and routers with existing analog servo drive find the Kanalog expansion board especially useful.

For CNC applications use KmotionCNC software with KFLOP+Kanalog and get highly advanced data capture capabilities to fully understand how the system is performing in terms of following error, speed, output, response, bandwidth, etc.

Kanalog works with many different Input/Output devices:

• KFLOP/Kanalog works well with ADVANCED Motion Control's drives that accept +/- 10V. analog and have differential encoder outputs for closed loop control.
