Special motion commands
4.8 Extended measuring function (MEASA, MEAWA, MEAC) (option)
Syntax
MEASA[<axis>]=(<mode>,<TE1>,...,<TE4>)
MEAWA[<axis>]=(<mode>,<TE1>,...,<TE4>)
MEAC[<axis>]=(<mode>,<measurement memory>,<TE1>,...,<TE4>)
Note
MEASA and MEAWA are non-modal; they can be programmed together in one block. However,
if MEASA/MEAWA is programmed together with MEAS/MEAW in the same block, an error
message is output.
