| P11Scalar: DevLong | 16 to 47: Time interval for timer.\nDefault value 33 corresponds to 1 ms. |
| FlagIgnoreStatusScalar: DevLong | If true: ignore status in reading position. |
Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State State Code |
This command gets the device state (stored in its <i>device_state</i> data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Status description |
This command gets the device status (stored in its <i>device_status</i> data member) and returns it to the caller. |
| CalibrateInput: DevDouble Calibrate position Output: DevLong Completion status |
Calibrate encoder. Compute offset from calibrate and current positions. |
| InitEncoderInput: DevVoid Output: DevLong Completion status |
Init encoder |
| SetCorrectionOffOnInput: DevLong 0 -> correction off, 1-> correction on (P9) Output: DevLong Completion status |
Set correction off or on setting P9 to 0 or 1 respectively. |
| DoReferenceInput: DevVoid Output: DevLong Completion status |
Start reference-seeking |
| CancelReferenceInput: DevVoid Output: DevLong Completion status |
Cancel reference |
Pipes:
Properties:
| Name | Description |
|---|---|
| ChannelDevUShort | Channel number. 0 or 1, selecting /dev/enc/0 or /dev/enc/1. |
| ModeDevUShort | 0 -> current measurement 1 -> voltage measurement |
| SimulationModeDevULong | 0 real mode, 1 simulation mode |
| DeviceDirDevString | Directory containing the encoder device files, e.g. /dev/ik220. Devices are expetected to be named DeviceDir/channelNumber, e.g. /dev/ik220/0, /dev/ik220/1 etc. |
