Read Drive Signal Status

Usage

status = flex_read_drive_signal_status(u8 boardID, u8 axis, u8 returnVector);

Purpose

Reads the status of the drive signal when an active signal is detected.

Parameters

Parameter Discussion

axis is the axis to configure. Valid values are NIMC_AXIS1 through NIMC_AXIS30. On motion controllers that support fewer than thirty axes, configuring non-existent axes returns error –70006 (NIMC_badResourceIDOrAxisError). Refer to Axes for axis resource IDs.

returnVector indicates the desired destination for the return data generated by this function. Available return vectors include return data to the host (0xFF), to a variable (0x01 through 0x78), to an indirect variable (0x81 through 0xF8), and do not return data (0). Refer to Input and Return Vectors for more detailed information.

Note  The suffix _rtn on the function indicates that the data must be returned to the host. When this calling convention is used, no returnVector is required.

Using This Function

Use this function to read the status of the drive signal when an active drive signal is detected. If In-Position is active, bit0 = 1. If Drive Fault is active, bit1 = 1.

Tip  Use Read Motion I/O Data instead of this function for more options.
