This machine data defines the ramp-up and operating status of the digital drives on an axis-
specific basis. The status is generated during ramp-up in the SERVO and updated accordingly
when the machine data is accessed.
Bit 0 Drive off
Bit 1 Drive on (after establishment of drive link)
Bit 2 On-line (communications connection between NC and drive)
Bit 3 Bootstrapping (drive must be booted)
Bit 4 Connected in (drive has ramped up to setpoint)
Bit 5 Ready (drive in control circuit, power connected) ˆ= MD 11003.5
