Load Position ModulusLoads the position modulus for an axis.

Position Modulus (0) is the position modulus value in counts (servo axes) or steps (stepper axes). The modulus range is from 0 (default) to (231) – 1. | |||||||
Board ID is a unique number assigned by Measurement & Automation Explorer (MAX) used to send and receive commands and data to or from a specific NI motion controller. | |||||||
Axis is the axis to control. | |||||||
Inp Vect indicates the source of the data for this VI. Available input vectors include immediate (0xFF), variable (0x01 through 0x78), or indirect variable (0x81 through 0xF8). Refer to Input and Return Vectors for more detailed information. | |||||||
error in (no error) describes error conditions that occur before this VI runs. The default input of this cluster is no error. If an error already occurred, this VI returns the value of error in in error out. The VI runs normally only if no incoming error exists. Otherwise, the VI passes the error in value to error out. The error in cluster contains the following parameters:

Bd ID Out is provided for flow control. You can string together NI-Motion VIs by wiring the Bd ID Out terminal of one VI to the Board ID terminal of the next VI. | |||||||
Resource Output is the Axis, Vector Space, ADC, or Encoder you wired into the VI. Use Resource Output to pass the resource to another VI and/or to display information about the device. | |||||||
error out contains error information. If error in indicates an error, error out contains the same error information. Otherwise, it describes the error status that this VI produces.

Using This VI
The Load Position Modulus VI sets the modulus used when the axis is operating in Modulus Position mode. It has no effect when the axis is operating in other modes. When a target position is loaded, it is interpreted within the boundaries of a modulus range.
Refer to the Set Operation Mode VI for a complete description of the Modulus Position mode.
