Fanuc alarm: 233 - DEVICE BUSY or P/S ALARM

When an attempt was made to use a unit such as that connected via the RS232C interface other users were using it. Or In the skip function activated by the torque limit signal, the number of

input. Therefore, the pulses cannot be corrected with one distribution.
Change the conditions, such as federates along axes and torque
limit, and try again.
