## Phidget Motor Position Controller.lvlib:MotorPositionControllerGetVelocity.vi

The most recent velocity value that the controller has reported.

- This value will be between -1 and 1 where a sign change (±) is indicitave of a direction change.
- Note that `Velocity` is merely an indication of the average voltage across the motor. At a constant load, an increase in `Velocity` indicates an increase in motor speed.
- The units of `Velocity` refer to 'duty cycle'. This is because the controller must rapidly switch the power on/off (i.e. change the duty cycle) in order to manipulate the voltage across the motor.

| Device In Device # Identification

| error in (no error) error in can accept error information wired from VIs previously called.

| status status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| code code is the error or warning code. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| source source describes the origin of the error or warning. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| Device Out Same as Device In

| error out error out passes error or warning information out of a VI to be used by other VIs.

| status status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| code code is the error or warning code. Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| source source describes the origin of the error or warning. Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
