XIST_A: actual value A, I32.
XIST_A is used to transmit the actual position value periodically. For details, see section
6.4.3 (1hex = 1LU).
NIST_B: Velocity Actual value B(32Bit), N4.
The servo parameter P310 is used as the reference variable, and the N4 type normalized
data corresponding to the current actual velocity of the servo driver is used as the return value
of the actual velocity of PLC. For details, see Section 6.1.4.
FAULT_CODE: Servo error code, U16.
The error code for the servo driver is returned to the PLC through this field. When no
error occurs, the return value is 0x0000. When an error occurs, the lower 8 bits fill the error
code and the higher 8 bits are fixed to fill 0xFF. See Chapter 7 for specific error codes.
WARN_CODE: Servo error code, U16.
This section is reserved.
USER_TX: user-defined functions.
Use parameter P316 to select feedback content. For details, see parameter P316
Definition.
