♦ Drive Function
Drive Function Operating Instructions
Subdivision set by SW5-SW8 four DIP switches to set the number of micro-step breakdown of the drive , which has 15 stalls micro-step . When users set the micro-step , you should stop the drive to run. See detailed breakdown set the table .
The output current is set by SW1-SW3 three DIP switches to set the driver output current , the output current total of eight files.
Automatic half current function the user can set the drive through SW4 automatic half current function. Quiescent current is set to half off said dynamic current , on said quiescent current and dynamic current is the same . General applications should SW4 is set to off, so that the motor and the drive to reduce fever , increased reliability . After a burst of about 0.4 seconds to stop automatically reduced to about half of the current (60 % of the actual value ) , reduced to 36% of the theoretical heat .
Signal Interface PUL + and PUL- control pulse signal positive terminal and a negative terminal , the pulse rising edge ; HIGH 4 ~ 5V, low level 0 ~ 0.5V. For reliable response to the pulse signal , the pulse width should be greater than 1.2μs. Such as when using +12 V or +24 V 1K or 2K series resistor required ;
DIR + and DIR- signal for the direction of the positive terminal and a negative terminal ; high / low signal , in order to ensure reliable motor commutation , the direction of the signal should be at least 5μs pulse signal is created. The initial direction of the wiring of the motor on the motor , interchange any phase windings ( eg A +, A- exchange ) can change the initial operation of the motor driving , the DIR- HIGH 4 ~ 5V, the low level 0 ~ 0.5V. Such as when using +12 V or +24 V 1K or 2K series resistor required .
ENA + and ENA- enable signal to the positive terminal and a negative terminal . This input signal is used to enable or disable . ENA + pick +5 V, ENA- connected low ( or internal optocoupler conduction ) , the drive current of the motor will cut off all phases of the motor is in a free state, then step pulse is not responding. When not required for this function, you can enable signal end vacant .
Positive and negative terminals B + and B- B -phase stepping motor connected windings ; positive and negative ends of the motor interfaces connected to A + and A- A phase stepper motor windings . When the A, B two-phase windings any negative exchange when a group , can reverse the motor direction .
Power connector DC power supply operating voltage range recommendations : DC36-110VDC, Power greater than 300W.
There are two red and green indicator lights drive . Where the green light for the power indicator on the drive power when the green light ; red fault indicator , when an overvoltage , overcurrent fault , the fault lights lit . 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.
Installation instructions for the drive Dimensions : 151 × 97 × 48mm, mounting hole spacing is 143mm. Both horizontal and vertical installation, we recommend the use of vertical installation . When installed, it should be close to the metal cabinet to facilitate cooling .

♦ quiescent current settings
SW4 = on the same quiescent current and dynamic current .
SW4 = off half the quiescent current of the dynamic currents ( recommended )
