Spindle override
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The spindle override can be defined via the PLC in binary or Gray coding.
The override value determines the percentage of the programmed speed setpoint that is issued to
the spindle.
With binary coding, the override is interpreted in %. 0% to 200% feed changes are possible, in
accordance with the binary value in the byte.
The following permanent assignment applies:

Binary values > 200 are limited to 200%.
The machine data:
MD12100 $MN_OVR_FACTOR_LIMIT_BIN (limit for binary-coded override switch)
can be used to additionally limit the maximum spindle override.
