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 . When users set the micro-step , you should 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 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 ; DIR + and DIR- signal for the direction of the positive terminal and a negative terminal ; ENA + and ENA- enable signal to the positive terminal and a negative terminal . Such as when using +12 V or +24 V 1K or 2K series resistor required
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 the A, B two-phase windings any set of positive and negative exchange , can reverse the motor direction .
Power Interface
DC power supply, operating voltage range of suggestions for 20-48VDC, Power greater than 100W.
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 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
The dimensions of the drive : 118 × 75.5 × 34mm, installation pitch of 112mm. 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 .
