The axisspecific feed rate override can be defined via the PLC in binary or Gray coding. With binary
coding, the feed value 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%.
Using the machine data:
MD12100 $MN_OVR_FACTOR_LIMIT_BIN (limit for binary-coded override switch)
the maximum axis-specific feed rate override can be additionally limited.
In gray coding, the following codes are assigned to the individual switch settings:
