Stepper Motor Driver Specification


Overview

The SC2M860D is a new generation microstep stepper motor driver which applies original imported chips. Due to the adoption of the advanced bipolar constant-current chopper driver technology, it shows stable operation, provides excellent high torque. Moreover, it significantly reduces the noises and vibration of the operating motor. The SC2M860D has the feature of low-noise, low-vibration and low-heating. The SC2M860D is AC24-60V power supply. It applies to 2-phase hybrid stepper motor under 6.0A current. The M660A has 14 kinds of microsteps. The maximum step number is 51200 steps/rev (microstep is 1/256). The peak operating current ranges 2.0-6.0A., and the output current has 8 stalls. The SC2M860D has automatic semi-flow, self-test, over-voltage, under-voltage, over-current protection functions.


Applications

It can be applied in a variety of small scale automation equipment and instruments, such as labeling machine, cutting machine, packing machine, drawing machine, engraving machine, CNC machine and so on. It always performs well when it is used in equipment which requires for low-vibration, low-noise, high-precision and high-velocity.

Driver functions descriptions

Driver function Operating instructions
Output currentsetting

Users can set the driver output current by SW1-SW3 three switches

.The setting of the specific output current, 

please refer to the instructions of the driver panel figure.

 Microstep setting

Users can set the driver Microstep by the SW5-SW8 four switches.

 The setting of the specific Microstep subdivision, 

please refer to the instructions of the driver panel figure.

 Automatic halfcurrent function

Users can set the driver half flow function by SW4.

 "OFF" indicates the quiescent current is set to half of the dynamic current, 

that is to say, 0.5 seconds after the cessation of the pulse, 

current reduce to about half automatically. 

"ON" indicates the quiescent current and the dynamic current are the same. 

User can set SW4 to "OFF", in order to reduce motor and driver heating and improve reliability.

 Signal interfaces

PUL+ and PUL- are the positive and negative side of control pulse signal;

 DIR+ and DIR- are the positive and negative side of direction signal; 

ENA+ and ENA- are the positive and negative side of enable signal.

 Motor interfaces

A+ and A- are connected to a phase winding of motor;

 B+ and B- are connected to another phase winding of motor.

 If you need to backward, one of the phase windings can be reversed.

 Power interfaces

It uses AC power supply. Recommended operating voltage is 24VAC-60VAC,

 and power consumption should be greater than 350W.

 Indicator lights

There are two indicator lights. Power indicator is green.

 When the driver power on, the green light will always be lit. Fault indicator is red, 

when there is over-voltage or over-current fault, 

the red light will always be lit; after the driver fault is cleared, 

if re-power the red light will be off.

 Installationinstructions

Driver dimensions:142×99×48mm, please refer to dimensions diagram.

 Please leave 10CM space for heat dissipation. During installation, 

it should be close to the metal cabinet for heat dissipation.


Signal interface details:

The internal interface circuits of the driver are isolated by the opt coupler signals, R in the figure is an external current limiting resistor. The connection is differential. And it has a good anti-jamming performance.

PhenomenonReasonSolution
 The red indicator is on.1. A short circuit of motor wires.Inspect or change wires
2. The external voltage is over or low than the driver’s working voltage.Adjust the voltage to a reasonable rang
