(b) Operating state by axis
According to exercise from “Chapter 8.1.2 Current State Reading,” it is a signal of “Operating” for each axis. It turns on
when it is operating. Direct Start command can not be configured while it is running hence configuration will only be
configured when it is not running. If you execute Direct Start while it is running, the “error 221” would be appeared.
(c) Error state for each axis
According to exercise from “Chapter 8.1.2 Current State Reading,” it is a signal of “Error state” for each axis. It turns on
when an error occurred. Operation will only work when there is no error. If you want to operate a system regardless of
errors, you can just inactivate the function.
