Stepper Drive

DM860/DM860H 步进驱动器

Signal interface PLS + and PLS - are the positive and negative ends of the control pulse signal; DIR + and DIR - are the positive and negative
ends of the directional signal; ENA + and ENA - are the positive and negative ends of the enable signal. 24V need to string 2K resistance
Motor interface A + and A- are connected to the positive and negative terminals of the A-phase winding of the motor; B + and B- are
connected to the positive and negative terminals of the B-phase winding of the motor. When A, B two-phase winding exchange, the direction
of the motor can be reversed.
Power connector DC power supply, the working voltage range is recommended for 20 - 50VDC. Power supply is greater than 100W;
according to the actual use of open look, the input is not more than DC40V is the right choice
Indicator light Drive has two lights red and green. The green light is the power indicator light. When the driver is powered on, the green light
is always on. The red light is the fault indicator light. When overvoltage or overcurrent fault occurs, the fault light is always on. After the fault is
cleared, the red light is off. When a drive fails, it can only be cleared by powering it on and re-enabling it.

全流／半流设定 SW4:ON= 全流 SW4：OFF= 半流（停止脉冲串时电流为设定值的—半，减少驱动和电机发热）
Full flow / half flow setting SW4: ON = full flow SW4: OFF = half flow (current stops at setpoint - halving pulse, reducing drive and motor
heating)
