GAP (Get Axis Parameter)

Most motion / driver related parameters of the PD42-1270 can be adjusted using e.g. the SAP command.

With the GAP parameter they can be read out. In standalone mode the requested value is also transferred

to the accumulator register for further processing purposes (such as conditional jumps). In direct mode

the value read is only output in the value ﬁeld of the reply, without affecting the accumulator.

Info

For a table with parameters and values that can be used together with this

command please refer to section

Internal function:

The speciﬁed value gets copied to the accumulator.
