Drive and computer communication line connection

Control port wiring

Pic 2 Common anode wiring method Pic 3 Common cathode wiring method

Pic 4 Differential signal input and output signal connection

Note: When the control signal voltage VCC = 24V, the current limiting resistor R = 3K;
When the control signal voltage VCC = 5V, the current limiting resistor R = 0;

Note: Hold time delay Brake delay time
Three, DIP switch setting

This series of drive current for the automatic tuning, so do not need to manually set the current, DIP switch corresponding functions are as follows:
Set the drive subdivision (see details on the driver
SW1~SW4 : are shell subdivision table)
SW5 ;: Set the motor direction
SW6 : Current self-tuning mode switch
SW7 : Working mode selection
SWS : Pulse input form selection
SW9 : Pulse edge selection
