Kanalog 1.0

Kanalog from Dynomotion adds analog and digital I/O to their KFLOP motion controller. Kanalog provides six types of various I/O which is enough to completely drive many types of machine tools.

Standard ±10V analog outputs may be used to drive analog motor drives. The analog outputs are true 12-bit DACS — not filtered PWMs that have slow response and ripple. All (eight) analog inputs and (eight) analog outputs are updated every servo sample time of 90 µs ( 11 kHz).

Relay drivers, opto inputs, opto outputs, differential encoder inputs, and LVTTL inputs and outputs are all included along with 112 screw terminals.

The photo shows Kanalog with a KFlop mounted with it and two cables that connect the two boards.

Setting Options

Set options on the KMotion Executive Program for both Kanalog and the required KFlop.

Analog Status

All of the Analog ADC readings and DAC settings can be observed by selecting the Kanalog tab of the analog I/O screen.

Digital Status

All of the digital I/O can be observed by selecting the Kanalog tab of the digital I/O screen.

Inputs are all on the left side of the screen and outputs are on the right. Outputs may be toggled by clicking on the state.

Position Controller Kit

Anew position controller from Parallax uses a quadrature encoder system to reliably track the position and speed of a wheel at all times. With the plastic encoder disk included in the kit, the position controller has a resolution of 36 positions per rotation; this equates to approximately 0.5 inches of linear travel per position using six-inch tires (not included). The position controller calculates and reports position and average speed data on command. This leaves the main processor free to handle more important tasks like reading GPS coordinates, processing sensor information, and maneuvering complex environments.
