Error Q BOOL 1 = Error
State Q BYTE 0 to 255 Error code
FRate
The feed rate in FC 18 can also be specified as:
1.
Cutting rate with unit m/min or feet/min
2. Constant grinding wheel surface speed in m/s or feet/s
These alternative velocity settings can be used only if this function is activated by the NC
program. Checkback signals for successful activation can be found in byte 84 on the axis
interface.
