As for wiring, it depends on the type and speed of your driver. If it is a single-stage drive, follow the circuit diagram. If it is bipolar drive, it is reCommended to use half winding, that is, com wire. The current limit is the same as that of single-stage drive, which is1.2a; : If the speed is relatively low, it is recommended not to use com wire in series, but the rated current becomes 0.84A, as shown in the wiring diagram below.
SST42D2 120 is an older series, and its heating and noise effects are not as good as those of 43D series. In addition, the round shaft and outlet are inconvenient for customers in the medical device industry, so it is suggested to change it to a customized model with 43D or SST42D2 120 characteristics. Please ask questions or talk privately if you don't understand.
