Meaning of the individual terms
Digit No. 7, 6 The servo loop module number is the number of the module on the
servo local bus. The modules are numbered from left to right in ascending
order. The far left module has the number 1.
Permissible values: 00 to 5
Digit No. 5, 4 The number of the servo loop connection determines the number of
the output on the selected HMS or SPC module.
Permissible values: 04 to 06 for SPC servo loop modules
04 to 12 for HMS servo loop modules
Note
• The value ”00 00 00 00” for MD 460* is permissible only if the spindle does not exist for
the control (MD 521*, bit 7=0).
