Bonjour
En consultant le 'user manual' de ton driver, je suis tombé sur cette phrase :
The second 1-bit selector is located on the top (S2 in figure 2), used to configure the voltage of control signals. For the safety of optically coupled, the factory setting is 24V, which no need to connect 2K resistors like the old drives, making it easier to use. When the voltage of the control signal is 5V, the S2 must be set to 5V, otherwise, the motor won't work.
A tout hasard, ce pourrait être la cause de ton problème si tu as laissé le switch S2 en config usine, c'est juste une idée.
Cordialement Jean-Luc
