(Default)
Validation timing
Axis
Specify the number of
the axis which is to be
controlled
USINT
Refer to Functions of
Section 2.2.
(The variable value
must be set)
When Enable is
TRUE

Output Parameters
Parameter
name
Function Data type Valid range
Valid TRUE when the output of the instruction is valid. BOOL TRUE / FALSE
Busy TRUE while the instruction is being executed. BOOL TRUE / FALSE
Error
TRUE while there is an error in the execution of the
instruction.
BOOL TRUE / FALSE
ErrorID
Contains the error code when an error occurs. Please
refer to section 12.2.
WORD
AxisErrorID
When Valid is TRUE, the value of ErrorID , xxx (hex)
indicates that the servo drive releases an alarm and xxx
is the alarm code that the servo drive reports. For
example, AL303 of the servo drive means the value of
ErrorID is 303 (hex).
