Product Overall View
RS-485 HS68D is the closed loop stepper drive of RS-485 ModBus series drive.It uses the latest 32bit digital processing technology.The drive control algorithm adopts advanced variable current technology and advanced frequency conversion technology,so small heating, small motor vibration and running smooth. The user can set any ID address within 1-255 and any current value in the rated current to meet the application needs in most occasions.Due to the built-in micro-step technology, the subdivision effect can be achieved even under the condition of low subdivision.

DIP switches Setting
RS-485 Modbus drive use 8 DIPs switches to set RS485 address, Baud rate and end matched resistor selection function. Details as following.
Note: The low 5 RS485 IDs set by DIPs, the 2 high RS485 IDs set by PC.
RS485 ID Table
ID | S1 | S2 | S3 | S4 | S5 |
Reserved(default) | On | On | On | On | On |
1 | Off | On | On | On | On |
2 | On | Off | On | On | On |
3 | Off | Off | On | On | On |
4 | On | On | Off | On | On |
5 | Off | On | Off | On | On |
…… | …… | …… | …… | …… | …… |
30 | On | Off | Off | Off | Off |
31 | Off | Off | Off | Off | Off |
Remark：RS485 ID calculating formula： ID=1*S1+2*S2+4*S3+8*S4+16*S5,default value is 0，0 means broadcast value,can set other high addresses through PC.
RS485 Baud Rate Table
Baud Rate | SW6 | SW7 |
Default(9600Hz,set by PC) | On | On |
19200Hz | Off | On |
38400Hz | On | Off |
57600 Hz | Off | Off |
CAN end resistor selection SW8：off=RS485 R off, default is off；
on= RS485 R on
Note：The end network driver need to set SW8=on.
