| EthercatDevice_QECR00MP3S | 0x00000bc3 | 0x0086d0d9 |
語法
int encoderDirectionRead(int encoder);
參數
[in] int encoder
The specified encoder number:
| 定義 | 值 | 描述 |
| ECAT_ENCODER_1 | 0x01 | Encoder 1 on the EtherCAT slave device. |
| ECAT_ENCODER_2 | 0x02 | Encoder 2 on the EtherCAT slave device. |
| ECAT_ENCODER_3 | 0x03 | Encoder 3 on the EtherCAT slave device. |
| ECAT_ENCODER_X | 0x11 | Encoder X, which mapping is determined by the configMachineAxisMapping(). |
| ECAT_ENCODER_Y | 0x12 | Encoder Y, which mapping is determined by the configMachineAxisMapping(). |
| ECAT_ENCODER_Z | 0x13 | Encoder Z, which mapping is determined by the configMachineAxisMapping(). |
回傳值
Return the current direction of the specified encoder. A return value of 0 indicates forward rotation, while a return value of 1 indicates reverse rotation. If the returned value is less than zero, it indicates an 錯誤代碼.
備註
This function must be called after a successful execution of EthercatMaster::start() and before EthercatMaster::stop(). This function is blocking and cannot be called within the callback functions.
