SmartEnergy
current up step
Sets the current increment step. The current
becomes incremented for each measured Stall-
Guard2 value below the lower threshold see
SmartEnergy hysteresis start).
Current incre-
ment step size:
Scaling: 0. . . 3: 1, 2, 4, 8
0: slow increment
3: fast increment / fast reaction to rising load
0. . . 3

SmartEnergy
hysteresis start
The lower threshold for the StallGuard2 value
(see SmartEnergy current up step).

StallGuard2
filter enable
Enables the StallGuard2 filter for more precision
of the measurement. If set, reduces the mea-
surement frequency to one measurement per
four fullsteps. In most cases it is expedient to
set the filtered mode before using CoolStep. Use
the standard mode for step loss detection.
0 - standard mode
1 - filtered mode

StallGuard2
threshold
This signed value controls StallGuard2 threshold
level for stall output and sets the optimum mea-
surement range for readout. A lower value gives
a higher sensitivity. Zero is the starting value.
A higher value makes StallGuard2 less sensitive
and requires more torque to indicate a stall.

SmartEnergy
actual current
This status value provides the actual motor cur-
rent setting as controlled by CoolStep. The value
goes up to the CS value and down to the portion
of CS as specified by SEIMIN.

Stop on stall
Below this speed motor will not be stopped.
Above this speed motor will stop in case Stall-
Guard2 load value reaches zero.

Chopper syn-
chronization
This parameter allows synchronization of the
chopper for both phases of a two phase motor
in order to avoid the occurrence of a beat, espe-
cially at low velocities.
