*) Please note that the fullstep setting as well as the half
step setting are not optimized for use without an adapted
microstepping table. These settings just step through the
microstep table in steps of 64 respectively 32. To get real
full stepping use axis parameter 211 or load an adapted
microstepping table.

ref. switch tolerance
For three-switch mode: a position range, where an
additional switch (connected to the REFL input) won't cause
motor stop. See section 6.1 for details.

snapshot position
For referencing purposes, the exact position at hitting of the
reference switch can be captured in this parameter. A
dummy value has to be written first to prepare caption.

max. current at rest
In contrast to the standby current, this current limit
becomes immediately active when the motor speed reaches
zero. The value represents a fraction of the absolute
maximum current:
0 – no change of current at rest (default, 100%)
1..7 – 12.5%..87.5%
See the TMC428 datasheet for details. Normally not used,
use parameters 6 and 7 instead!

A ramping parameter, can be adjusted in special cases,
automatically calculated by setting the maximum
acceleration (e.g. during normal initialisation). See the
