Product Specifications: This product is the latest DSP digital two-phase stepper drives, authentic guarantee, a penalty at ten! Particularly suitable for use in the engraving machine, compatible DM860, MA860H, MA860, M860 these products. Lower heat, less noise and better stability.
   AC and DC power supply can be used with a wide voltage range, the highest voltage not exceeding 90V, the minimum of not less than 24V, recommended operating voltage range of 28-80V.
         You can drive 57,85,86 series and 110 series two-phase hybrid stepping motor. There are 16 micro-step breakdown of the number of species, the maximum number of steps for 51200Pulse / rev; operating peak current range 2.4-7.2A, eight stalls output current, the current resolution of about 0.6A, with automatic half-current, over-voltage, overcurrent protection.
        Mainly used in a variety of medium-sized automation equipment, such as: a variety of engraving engraving and milling machine, CNC cutting machine, packaging machinery, automated assembly equipment. In the low-noise, high speed device applications excellent special effects.

Instructions

Number of micro-step breakdown of the set


By SW5-SW8 four DIP switches to set the drive micro-step breakdown of the number of its total of 16 stalls micro-step. When the user sets micro-step, stop the drive to run. Specific micro-step breakdown of the number of the setting, the drive surface layout instructions.

Output current setting


By SW1-SW3 three DIP switches to set the driver output current, the output current eight stalls. Specific output current, please drive surface layout instructions.

Automatic semi-flow function


Users can set the drive SW4 automatic semi-flow feature. Quiescent current is set off, said half of the dynamic current, on the static and dynamic current is the same current. General applications SW4 should be set to off, so that the motor and the drive to reduce fever, increased reliability. After the burst of about 0.4 seconds to stop automatically reduced to about half the current (60% of the actual value), heat theoretically reduced to 36%.

Signal Interface


PUL + and PUL- control pulse signal for the positive terminal and a negative terminal; DIR + and DIR- for direction signal positive terminal and a negative terminal; ENA + and ENA- to make the positive terminal and a negative terminal signal.

Motor interface


Positive and negative terminals B + and B- then stepping motor phase winding B; positive and negative terminals A + and A- A stepper motor connected to the phase windings. When the A, B two-phase windings exchange, can reverse the motor direction.

Power Interface


AC supply voltage range is recommended for 18-80VAC, Power greater than 300W, voltage does not exceed 90VAC and not less than 24VAC.

Indicator


Drive has two red and green lights. Where the green light for the power indicator light, when the drive is powered green light; red fault indicator, when an overvoltage, overcurrent fault, the fault light is on. After the fault is cleared, the red light is off. When a drive fails, only the power on again and re-enabled in order to clear the fault.
