A library for Arduino to control BLVD20KM or BLVD40NM which is a brushless motor driver of Oriental Motor.
To use motor driver in 115200bps via RS485 modbus, set switch 2 like this
| No | State | Role |
|---|---|---|
| 1 | OFF | Baudrate |
| 2 | OFF | Baudrate |
| 3 | ON | Baudrate |
| 4 | OFF | Not used |
| 5 | ON | Use Modbus Protocol |
| 6 | OFF | Not used |
| 7 | ON if the motor driver is end of RS485 chain | End point register |
| 8 | OFF | Address upper bit |
Baudrate configuration
| No1 | No2 | No3 | Baudrate |
|---|---|---|---|
| OFF | OFF | OFF | 9600 |
| ON | OFF | OFF | 19200 |
| OFF | ON | OFF | 38400 |
| ON | ON | OFF | 57600 |
| OFF | OFF | ON | 115200 |
Switch 3 means address of motor driver. If you use multiple motor, set different address for each motors.
Example project communicate with a driver which address is 1.
| No | Role |
|---|---|
| 1 | NC |
| 2 | GND |
| 3 | TR+ |
| 4 | NC |
| 5 | NC |
| 6 | TR- |
| 7 | NC |
| 8 | NC |
| Arduino | Uart to RS485 | motor driver |
|---|---|---|
| None | A | TR+ (LAN 3) |
| None | B | TR- (LAN 6) |
| TX1 | DI | None |
| RX1 | RO | None |
| D4 | RE | None |
| D5 | DE | None |
| 5V | 3~6V | None |
| GND | GND | GND (LAN 2) |
I checked connection with using some RS485 tranceiver. Ex: SparkFun Transceiver Breakout - RS-485, sp3485-breakout or sp3485-one-line-breakout.
See example project and header file.
