170 SmartEnergy
hysteresis
Sets the distance between the lower and the
upper threshold for StallGuard2 reading. Above
the upper threshold the motor current becomes
decreased. Hysteresis: ([AP 172] + 1) ∗ 32
Upper StallGuard threshold: ([ AP 172]+[ AP 170]+
1) ∗ 32
0. . . 15 RW
171 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 RW
172 SmartEnergy
hysteresis start
The lower threshold for the StallGuard2 value
(see SmartEnergy current up step).
0..15 RW
173 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

174 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.

180 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.
Actual motor current scaling factor:
0. . . 31: 1/32, 2/32, . . . 32/32
0. . . 31 R
181 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.
