Digit No. 1, 0: Local axis number
The control automatically enters the local number of the axis here.
Digit No. 3, 2: Code digital drive
Code 10(-15) assigns the address to 611-D (611-D servo loop or digital setpoint channel).
Codes 1-9, 11-15 are reserved for expansions in the future and are interpreted as for 00 or 10.
The code must be entered by the user.
Digit No. 5, 4: SPC/HMS setpoint output
Permissible values for digital drives are the values 01 and 02:
01: PCU slot 1 (for MSD permanent indirect measuring system)
02: PCU slot 2 (free direct or indirect measuring system)
Digit No. 7, 6: Logical drive number / Servo loop module number
The logical drive number is entered here for digital drives.
Input range (00..15): 00: No submodule available
01..15: According to logical drive number
For more detailed information see MDD
Input range (00..30): 00: No submodule available
(SW 5 and higher) 01..30: Logical drive number
Notes:
• See Section 5, Machine Data Dialog, for the servo loop assignment.
• Up to SW 4: Only 14 real axes can be defined with a fictitious axis.
