There is no more space available on a device. If this error is received for a disk file it indicates that the disk is full (if there are many small files on the device this error indicates the directory is full). If this error is received for a servo device it indicates that an attempt has been made to assign too many servo axes to a single CPU. Delete unneeded disk files or use another drive or diskette. Reconfigure your system so the maximum number of axes per CPU is not exceeded.
