l Power Interface DC +, DC -
DC 24 ~ 50DC, usually a linear power supply (see Appendix: linear power supply schematic) power supply, the user should be noted that the filtered rectified power supply ripple voltage, not more than 50VDC, so as to avoid damage to the drive, linear power supply rated output current should be larger than the current drive to set 60%. When using switching power supply should be attention to the nominal rated output current, to choose a match with the motor phase current switching power supply. General, the higher the supply voltage, the motor torque output greater steps to avoid the phenomenon of high-speed lost, but also lead to increased low-speed vibration, as well as fever, should be used with the mechanical requirements of a reasonable adjustment under the on-site power supply voltage, we adopted the test concludes that the most ideal voltage range of between 30VDC ~ 40VDC.
Should pay special attention to input power wiring polarity, DC + for the power supply cathode; DC-for power, the wrong cable can cause damage to the drive!
In order to meet electromagnetic compatibility requirements drive is recommended to use the company-driven design of DC power supply.
l Set output current
The Driver Design 8 file output current choices and drive the encoding switch (SW1 SW2 SW3) setting, the current size to the maximum nominal. SD-2H044MA type drives available 4.25A maximum output current, the current setting resolution of 0.41A. Coding switch (SW1 SW2 SW3) for each combination of a state represents a current value of the output settings, reference the table below:

In setting this parameter will make sure that the drive is not the power or increase power but the motor is not running the state, this would avoid the current mutation of the drive power inverter segment generated shocks. Parameter setting complete please turn off the power to re-power after the new parameters will be effective. Non-standard operations may result in damage to the drive!
l Automatic Semi-current
Drive control pulse signal to stop imposing 0.1 seconds or so, will automatically enter the semi-current state, this time to run when the motor phase current 50% to reduce power consumption and protect the motor, a new control pulse received after the drive automatically flow out of the slightest state, this function is performed by the drive panel DIP switches (SW4) to set: OFF - Automatic Semi-stream and effective, ON - Automatic semi-flow is invalid. Semi-automatic current setting it is also imperative in the drive does not power up or power-up but the motor is not running, the set finished please turn off the power to re-power after the new parameters will be effective.
l Set the drive segment
Users can drive the panel by adjusting the DIP switch (SW5 SW6 SW7 SW8) the state to set up 15 kinds of sub-modes. The 15 kinds of sub-model, basically covering all users of motor step angle requirements. The setting parameters in the table below or drive enclosure silk screen panel diagram. It is equally imperative to set the number of segments in the drive does not power up or power-up, but when the motor is not running. Please turn off the power setting is completed, re-power after the new parameters will be effective.

Users can drive by changing the internal circuit board jumper switch (J1, J2) to receive control of the state to set the pulse form. Switch jumper J1 is defined as: ON - Pulse plus direction mode; OFF - double-pulse mode. Jumper switch J2 is defined as: ON - pulse rising edge and effective; OFF - pulse falling edge and effective. The setting parameters in the table below.
Usual, there are four forms of control pulses as shown below: Pulse plus direction mode (PULS + DIR) is the logic, dual-pulse mode (CW + CCW) is the logic, pulse plus direction mode (PULS + DIR) negative logic, dual - pulse mode (CW + CCW) negative logic. Pulse plus direction mode, the drive pulse control pulses from the receiver port (PULS +, PULS-) input, which drives the direction of the port (DIR +, DIR-) high and low level of the decision of the motor rotation direction; double-pulse mode, the drive pulse port (PULS + , PULS-) is transferred to receive instruction pulse drives the direction of the port (DIR +, DIR-) to receive instructions reverse pulse. Whatever the form of a control pulse, drives the internal high-speed optocoupler is to accept it. Control impulses settings must be in the drive does not power up or power-up but the motor is not running, do not turn off the power to set the new parameters is completed to take effect.
l protection
When the input power over-voltage, output over-current, and white short-circuit any alarm generated an alarm when the driver of the red status indicator panel will be lit at the same time enable the automatic cut off the motor, the motor is offline. To maximize the protection of drivers and motor safety.
Control Interface
l-pulse input interface PULS +, PULS -
Stepping Pulse Interface PULS: stepper motor driver control device to the upper pulse sent into stepper motor angular displacement, the drive pulse signal for each receive a PULS, to drive a stepper motor rotating a step angle, PULS frequency and stepper motor speed is proportional to. The signal reception as a standard differential receiver circuit, recommended command pulse output mode differential, there are also practical instruction open collector pulse output mode, in the standard wiring diagram, we will detail. For the best input requirements, this signal preferably 1:1 duty cycle, pulse frequency of requests is not more than 500KHz; pulse width requirement is not less than 1¦ÌS, detailed requirements see below.CCW

l direction input DIR +, DIR -
Direction-level signal DIR: This decision signals the direction of motor rotation. For example, this signal is high when the motor is clockwise rotation, this signal is low compared to the opposite direction when the motor counter-clockwise rotation, such a change to the way we call pulse plus direction mode. In addition, there is a double-pulse drive mode: accept the two-way drive pulse signal (CW; CCW), when one way (eg, CW) has a pulse signal, motor forward run, when the other route (such as the CCW) has a pulse signal motor reverse run. When using double-pulse drive mode, the pulse input interface PULS +, PULS-link pulse signal is being transferred CW, the direction input DIR +, DIR-link reversal pulse signal CCW. The signal receiving the same as a standard differential receiver circuit.

If the drive input signal to current signal requirements: 7mA ¡Ü high current ¡Ü 18mA;-18mA ¡Ü low current ¡Ü 0.2mA. Pulse frequency of requests is not more than 500KHz; pulse width requirement is not less than 1¦ÌS; pulse signal of the drive current requirements for 7-18mA.
l enable signal interface ENBL +, ENBL-:
Enable signal ENBL: drive up and down with the electric power to electric-pass operation will drive rapid aging, in order to avoid this situation. The drive is designed to enable the signal (ENBL) input ports, commonly known as the de-electromechanical-level signals (FREE). Users can always control this signal, when this signal is active, the drive will automatically cut off the motor winding currents, the motor is in a free (no power) state. When this signal is not connected by default to be invalid state, then through the motor winding current can function properly. The signal receiving circuits and pulse input interface circuit line, this signals an effective means for making the internal drive to receive optocoupler conduction.
l Electric Power Output:
This product is suitable for driving current of 4.25A relative to the following four lines, six lines or eight lines of any one phase or two four-phase stepper motor. A total of five kinds of motor winding connection access method, see below:
Based on the wiring diagram shown in five kinds of ways should be reasonable to set driver output current, in theory, the greater the current setting, the greater the motor torque output can be used to avoid the phenomenon of motor speed lost step, but it can also cause the motor temperature l. In general, high-speed output wiring its output current set in the motor phase current rating of 1.4 times; high torque output of the wiring of its rated output current set in the motor phase current 70%. Practical applications, should be set in the motor current long-term surface temperature does not exceed +80 ¡æ range.
