The following connecting diagram shows the connection of ADTECH Q2BYG404MA driver and
85BYGH830A stepping motor:
Remark:
1) Please adjust the subdivision of driver and the current code switch properly when using. The
subdivision of driver is recommended to be 64 subdivisions, and the current to be 1.2 times of motor
current.
2) The power supply for self-lock removing function is external 5V DC power. If it is 12V DC power,
please connect in series a 1K resistor, whose power should be over 1/4W, to the pin of MF. Connect in
series a 2K, over 1/4W resistor if it is 24V DC power.
