Write position values
Positions are specified as the number of increments (incr.)
and refer to the measuring system length used (total length =
2
16
incr. = 65536 incr.). 2 bytes are used for transmission.
The high byte is the higher-value byte, the low byte is the
lower-value byte.

Note when loading position values:
When a position is reached, a flag is set internally in the
SPC11, thereby registering that the position has been
reached. If, when an intermediate position has been reached,
a new position value for the same intermediate position is
loaded and a positioning order to move to this position is
issued, the drive will remain in the current position.
