Stepper Outputs
Stepper output resources generate the step pulses required for stepper axis control. They operate like the DAC output in a servo axis.
NI-Motion supports the two industry-standard stepper output configurations: Step and Direction, or CW/CCW pulses. Refer to Configure Stepper Output for more information about these output configurations. The following table lists the resource IDs for stepper outputs:
| Resource Name | Resource ID |
| Stepper Output 1 | 0x41 (65) |
| Stepper Output 2 | 0x42 (66) |
| Stepper Output 3 | 0x43 (67) |
| Stepper Output 4 | 0x44 (68) |
| Stepper Output 5 | 0x45 (69) |
| Stepper Output 6 | 0x46 (70) |
| Stepper Output 7 | 0x47 (71) |
| Stepper Output 8 | 0x48 (72) |
| Stepper Output 9 | 0x49 (73) |
| Stepper Output 10 | 0x4A (74) |
| Stepper Output 11 | 0x4B (75) |
| Stepper Output 12 | 0x4C (76) |
| Stepper Output 13 | 0x4D (77) |
| Stepper Output 14 | 0x4E (78) |
| Stepper Output 15 | 0x4F (79) |
Using Stepper Outputs Nine Through Fifteen
Complete the following steps to use stepper outputs nine through fifteen:
- Open the desired VI in LabVIEW.
- View the block diagram.
- Right-click the appropriate terminal and select Create»Constant.
- Click the drop-down arrow on the constant and select Other.
- Type the selected stepper output number (in decimal) for stepper outputs nine through fifteen.
