MC_Power.Status output. MC_Stop.Execute might be held high, preventing motion.
The function block is not applicable for the external axis specified
Motion aborted due to axis alarm. It is also possible that a software limit has been
exceeded.
Axis ID does not correspond to an axis configured on the system. Verify the value of
AxisNum matches a logical axis number in the configuration. Tip: Make sure AXIS_REF is
properly declared as a VAR or VAR_GLOBAL in all relevant POUs.
Buffer mode does not correspond to a valid enumeration value.
Direction does not correspond to a valid enumeration value.
Acceleration is less than or equal to zero.
Deceleration is less than or equal to zero.
Velocity parameter is negative.
Jerk is less than or equal to zero.
The specified external axis may not be used. A physical axis is required.
The axis must be configured as a rotary type for this function block to be applicable.
The DataType connected to a function block parameter specified as ANY type does not
match the required data size. Right click on the function block and select “Object
Properties” to determine which parameters are ANY type.
Example 1
In the first example the speed is low enough and the deceleration high enough that the axis can stop within one
revolution. This is the easiest condition.
