The converted, physical spindle number is always output as the address extension in the auxiliary function
output.
Boundary conditions
• Switchable channel spindles are not a substitute for the Axis replacement function.
• You can only switch spindles, which have been assigned to the channel by means of configuration.
• If spindles, which are presently active in another channel, are designated for switchover, either the "AutoGet"
function is triggered for the physical spindle or alarm 16105 "Assigned spindles do not exist" is output,
depending on the configuration variant.
• If SD42800 $SC_SPIND_ASSIGN_TAB[<n>] is specified by the PLC or from HMI, then the channel whose
table is changed should be in Reset status or the spindle to be changed should not be used in the running part
program.
A synchronized response can be achieved by means of a STOPRE preprocessor stop.
• The multiple mapping of logical to physical spindles is not prevented in the NC. However, with the display of
logical spindle in the operator interface, there are ambiguities corresponding to the change table.
• Spindle conversion operates on spindles via FC 18.
Activation
SD42800 $SC_SPIND_ASSIGN_TAB[<n>] is enabled by setting the following machine data setting:
MD20092 $MC_SPIND_ASSIGN_TAB_ENABLE=1
Basic setting SD42800
After switching on the NC with the commissioning switch in setting 1 (delete SRAM) SD42800
$SC_SPIND_ASSIGN_TAB[<n>] is in the basic setting.
The numbers of the logical and physical spindles are identical.
SD42800 $SC_SPIND_ASSIGN_TAB[1] = 1
SD42800 $SC_SPIND_ASSIGN_TAB[2] = 2
SD42800 $SC_SPIND_ASSIGN_TAB[3] = 3
SD42800 $SC_SPIND_ASSIGN_TAB[4] = 4
SD42800 $SC_SPIND_ASSIGN_TAB[5] = 5
