Overvoltage, under voltage, overcorrect, phase short circuit protection. Pulse signal, PUL+ is the positive end of pulses input pin. PUL- is the negative end of pulse input pin. DIR signal: DIR+ is the positive end of direction input pin.
DIR- is the negative end of direction input pin. Enable signal: ENBL+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver.High level for enabling the driver and low level for disabling the driver. ENBL- is the negative end of direction input pin. PCs control signals can be active in high and low electrical level. When the high electrical level. Is active, all control negative signals will be connected together to GND. Is active, all control positive signals will be connected together to public port. Examples(Open collector &PNP), please check them. Input port circuit (Yang connection). 2 Input port circuit (Yin connection). R must connect in the control signal part. Function choice (Using DIP pins to achieve this function). 1 Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table. SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current and ON meaning that standstill is set to be the same as the selected dynamic current. The first three bits (SW 1, 2, 3) of the DIP switch are used to set the dynamic current. Closest to your motors required current. Semi-flow function is that there is not step pulse after 500 ms, the driver output current automatically reduced to 70% of rated output current, which is used to prevent motor heat. +V: Power supply, 1650 VDC, Including voltage fluctuation and EMF voltage. The max current is 5A. (2) A+ A- B+ B-Connecting 2 phase stepper motors. The driver & 2-phase hybrid stepping motor use four-wire connection, the motor can be connected in parallel & series bipolar. As for bipolar connection, it is higher performance with high-speed, but the current of driver is larger (it is 1.73 times more than the motors winding current). Connecting in series, the drivers current is equal to the motor winding one. There should be 20mm of space, it cant be placed next to other heating devices, to avoid dust, oil mist, corrosive gas, humidity and strong vibration places. 1, the status on lights indication.
RUN: green, normal work light. ERR: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection. Motor doesnt run, without holding torque. Wrong connection of stepper motor.
RESET signal is effective when offline. Motor doesnt run, butmaintains holding torque. Adjust PMW & signal level.
Change connection for any of 2 wires. Motors holding torque is too small.
Too small relative to current setting. Driver does not match with the motor. The power is 350Watts, and the output voltage is 36VDC.
