Drive function
Operating Instructions
Set the number of segments
By the SW5-SW8 four DIP switches to set the number of micro-step breakdown of the drive , which has 15 stalls micro-step . Users set the micro-step
When broken down , stop the drive to run. See detailed breakdown set the table .
Output current setting
The SW1-SW3 three DIP switches to set the driver output current , the output current total of eight files.
Automatic half current function
Users 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 drive
Reduce heat , improving reliability . After a burst of about 0.4 seconds to stop automatically reduced to about half of the current ( actual value
60% ) , the theoretical heat to 36 %.
Signal Interface
PUL + and PUL- control pulse signal positive terminal and a negative terminal , the pulse rising edge ; HIGH 4 ~ 5V, low
When 0 ~ 0.5V. For reliable response to the pulse signal , the pulse width should be greater than 1.2μs. If using +12 V or +24 V
1K or 2K takes string resistance ;
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, directional radio
No pulse signal should be at least 5μs established. The initial wiring of the motor with the motor running direction is related to any swap
Phase winding (e.g., A +, A- exchange ) can change the initial operation of the motor driving , the DIR- HIGH 4 ~ 5V, LOW
When 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
- Then low ( or internal optocoupler conduction ) , the drive current of the motor will cut off all phases of the motor in a free state ,
At this step pulse is not responding. When not required for this function, you can enable signal end vacant .
Motor Interface
Positive and negative terminals B + and B- phase winding connected to the stepper motor B ; A + and A- negative terminal connected to the A-phase stepper motor winding. When A,
B positive and negative exchange any two-phase windings of a group , can make the reverse motor direction .
Power Interface
AC or DC power supply operating voltage range recommendations : DC36-110VDC, or AC20-AC90V, electricity
Source power greater than 300W.
Indicator
Drive has two red and green lights . Where the green light for the power indicator on the drive power when the green light ; red light is
Fault indicator , when an overvoltage , overcurrent fault , the fault lights lit . After the fault is cleared , the red light is off . When the drive
When a fault occurs , only the power on again and re-enabled in order to clear the fault.
Installation Instructions
The dimensions of the drive : 151 × 97 × 48mm, installation pitch of 143mm. Both horizontal and vertical installation, construction
Meeting with vertical installation. When installed, it should be close to the metal cabinet to facilitate cooling .
