Explanation of display fields MSD 1st screen
Drive status This display field describes the ramp-up and operating status of the digital drives.
This status is generated in the SERVO during start-up and then changed accor-
dingly in the display (SW 4: Drive MD 11008).
Possible data:
0 8OFF
1 8On (after the drive has returned status signal to SERVO)
2 8On-line (communication possible)
3 8Bootstrap (drive must be rebooted)
4 8Connected (drive ramp-up completed)
5 8Ready (drive under closed loop control, Power On)
Main spindle drive This display field describes the actual MSD drive, i.e. the one which has been
selected using softkeys drive +/–.
Ramp-up phase This display field contains the control word for the ramp-up control of the 611D
components and exists for each logical digital drive number (drive MD 11000).
The ramp-up state set by the SERVO is shown in the high byte and the state ack-
nowledged by the drive is shown in the low byte (see description drive status).
Possible information:
High byte 8Set ramp-up status
(SERVO)
Values: 0 5
Low byte 8Acknowledged ramp-up state (drive)
Values: 0 5
Possible display range: 0000 0505
