Drive Command
The command name is DR. The command drive as used at other instruments is available but behaves
differently.
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:
> DR QH qh qk ql en
If en (the energy transfer value) is omitted, the energy transfer
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:
> DR Q3 qh qk ql en
For powders (no more powder mode switch, qm is in Å-1):
> DR QM qm EN en
Driving the energy transfer alone is also possible, (using the last
given q values):
> DR 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)
