Details
One of the following attempts was made on an axis that can be switched to NC/auxiliary axis.
- A command was issued to an auxiliary axis from machining program.
- When there were more than one NC axis having a same name, a command was issued to
those axes from machining program.
- "NC axis control selection" signal was turned OFF while the NC axis was in motion.
- "NC axis control selection" signal was turned ON while the auxiliary axis was in motion.
Remedy
- Turn ON the "NC axis control selection" signal to set the auxiliary axis to NC axis when is-
suing a command to the axis from machining program.
- When more than one axis have a same name, let only one of the axes work as an NC axis.
- Do not change the "NC axis control selection" signal while the axis is in motion.
