my problem is a mystery to me, I have, to my knowledge, tried everything to get my running spindle motor. The spindle motor is a DC motor max. 180 volts, placed on the spindle motor is a Rotery encoder with the outputs A and B and Z (Z but I do not use). The breakout board (5-axes) is a Mach3 HG08, ordered (CNC4YOU) Axes X, Y, Z, A, work perfectly. The B input is used for the spindle motor. Inputs are: GND, Vcc, CK, CW, AND (AND not connected). The first 5 are connected to a DG2S-16035 Servo drive (with 8 inputs total) via a UTP cable. Input 1 (CK) 2 (CW) 3 (GND) 4 (NOT USED) 5/6 (VCC) 7 (external DC power) 8 (External DC gnd). Encoder input of the DG2S-16 035 is connected via a UTP cable to an encoder interface, and the encoder interface is reconnected to the Rotery Encoder on the spindle motor. summarized: I have all the wires, cables, checked for fractures, but all cables are good. The settings in Mach3 (see photos). I have to be sure all components exchanged with new components, ie, the DG2S-16 035, the External Braking Circult Connector, Encoder Interface, and even the Breakout board (HG08), the Rotery Encoder, on The spindle motor, the result was the same, no rotating spindle.
