Product Description

Factory Direct Sale Quality Small 2 Phase Stepper Driver Mini with Low Price Manufacturers and Suppliers. LICHUAN® is Small 2 Phase Stepper Driver Mini manufacturer and supplier in China.

Product Introduction

MC860H(E) mini is an 86 digital step drive developed based on high-performance and low-power-consumption ARM chips. It is provided with an intelligent regulator with a PID parameter self-regulation function, so the most appropriate parameters can be automatically generated for different motors without manual regulation, making the operation performance of motors be the best. The motor noise of this drive is very low, achieving a high cost performance.

Drive function description

Drive function	Instructions
Microstep subdivision setting	The number of micro-step subdivisions of the driver is set by four DIP switches SW5~SW8. There are 16 micro-step subdivisions in total. When the user sets subdivisions, the driver should be stopped first.For score setting, please follow the driver panelinstructions.
Output current setting	The output current of the driver is set by three DIP switches SW1~SW3, and its output current has 8 gears. For the specific output current setting, please refer to the driver panel description.
Automatic half -flow function	The user can set the automatic half-flow function of the driver through the SW4 switch. OFF means that the quiescent current is set to half of the dynamic current, and ON means that the quiescent current and dynamic current are the same.In general use, SW4 should be set to OFF to reduce the heat generation of the motor and driver and improve reliability. About 0.3 seconds after the pulse train stops, the current will automatically decrease by 50%(actual value55%), the calorific value is the oretically reduced by 65%.
Signal interface	PUL+and PUL- are the positive and negative ends of the control pulse signal; DIR+and DIR- are the positive and negative ends of the direction signal: ENA+ and ENA- are the positive and negative ends of the enable signal, ALM+ and ALM- are the alarm output.
Motor interface	A+ and A- are connected to the positive and negative ends of the A-phase winding of the stepping motor; B+ and B- are connected to the positive and negative ends of the B-phase winding of the stepping motor. When the A and B two-phase windings are exchanged, the direction of the motor can be reversed
Power connector	Use AC/DC power supply, the voltage range is 24~110VDC or 18~80VAC, the terminals are not divided into positive and negative poles, the recommended power supply is DC 48V, and the power is greater than 250W.
Indicator light	The drive has two indicator lights, red and green. The green light is the power indicator, when the driver is powered on, the green light is always on; the red light is the fault indicator, when there is an overvoltage or overcurrent fault, the faultThe light is always on.After the fault is cleared, the red light goes out. When the drive fails, only a power cycle and re-enable can clear the fault.
Installation Notes	The external dimensions of the driver are: 11 9 x76 x34mm, and the mounting hole distance is 112mm It can be installed horizontally or vertically (vertical installation is recommended). When installing, it should be close to the metal cabinet to facilitate heat dissipation.

Parameter setting

Subdivision precision, dynamic and half/full currents can be set for MC860-Mini Driver through 8-bit dial switch as follows:
