Description
ON: The FB is executed.
The velocity command value is set.
It can be specified with a sign.
The time taken for the servo motor to reach the rated
speed is set.
The time taken for the servo motor to stop from the
rated speed is set.
The rotation direction is specified.
MC_DIRECTION defined values can be used. Select
one of the following two values.
• mcPositiveDirection positive direction (1)
• mcNegativeDirection negative direction (2)
Description
It indicates that the velocity has reached the
specified value.
It indicates that the FB is in execution.
It indicates that the FB is controlling the axis.
It indicates that another FB has aborted the
execution of the FB.
When ON, it indicates that an error has occurred in
the FB.
The error code generated in the FB is returned.
