1=left stop switch disabled
0=left stop switch enabled
128
ramp mode
Automatically set when using ROR, ROL, MST
and MVP.
0: position mode. Steps are generated, when
the parameters actual position and target
position differ. Trapezoidal speed ramps are
provided.
1: velocity mode. The motor will run
continuously and the speed will be changed
with constant (maximum) acceleration, if the
parameter target speed is changed.

step interpolation
enable
Step interpolation is supported with a 16
microstep setting only. In this setting, each
step impulse at the input causes the
execution of 16 times 1/256 microsteps. This
way, a smooth motor movement like in 256
microstep resolution is achieved.
0 – step interpolation off
1 – step interpolation on
161
double step
enable
Every edge of the cycle releases a
step/microstep.
It does not make sense to
activate this parameter
for internal use.
Double step enable can be used with Step/Dir
interface.
0 – double step off
1 – double step on
162
chopper blank
time
Selects the comparator
blank time
. This time
needs to safely cover the switching event and
the duration of the ringing on the sense
resistor. For low current drivers, a setting of 1
or 2 is good. For higher current applications
like the TMCM-1060 a setting of 2 or 3 will be
required.
163
chopper mode
Selection of the chopper mode:
0 – spread cycle
1 – classic const. off time
164
chopper
hysteresis
decrement
Hysteresis decrement setting. This setting
determines the slope of the hysteresis during
on time and during fast decay time.
0 – fast decrement
3 – very slow decrement
