This is version 2.
It is not the current version, and thus it cannot be edited.

Drive Command
The command name is drive, as on other instruments.
dr may be defined as an alias.
Motors are driven as on other SICS instruments. With a single
drive command several motors may be driven.
Driving in reciprocal lattice units
Drive within scattering plane:
> drive qh qh qk ql en
If en (the energy transfer value) is omitted, the energy transer
is assumed as zero (in contrast to TASMAD, where it is the last used
value). It is an error to give less than 3 numbers, or to
drive outside the scattering plane.
To drive in 3 dimensions:
> drive q3 qh qk ql en
For powders (no more switch, qm is in Å-1):
> drive qm qm en
Driving the energy transfer alone is also possible, (using the last
given q values):
> drive en en
Analyzer and monochromator energies are represented by the virtual
motors ei, ki, ef and kf, as in TASMAD.
An error is signaled:
- when real motors are mixed with virtual motors like qh, en or kf
- when incompatible virtual motors are driven (like qh and qm)
