Key issues

Question 1: How many axes can CK3W-AX control at most? How many AX units can be installed in the same rack at most?

answer:

Single CK3W-AX can control up to 4 axes;

Whether it is a CPU rack or an expansion rack, a maximum of 2 CK3W-AX units can be installed.

Question 2: What is the core difference between CK3W-AX1414, AX1515, and AX1313?

answer:

AX1313: DirectPWM output, compatible with dedicated Delta Tau drivers;

AX1414: DA output (filtered PWM), lower cost;

AX1515: DA output (true DAC), with pure waveform and the highest accuracy, suitable for ultra precision servo.

Question 3: What encoders does CK3W-AX support? Which model do different encoders correspond to?

answer:

Digital Orthogonal Encoder, Serial Encoder: AX1313/414/1515

Sine and Cosine Encoder (1Vpp SIN/COS): AX2323

All models support UVW Hall signal input.
