smartEnergy
current minimum
(SEIMIN)
Sets the lower motor current limit for
coolStep operation by scaling the CS (Current
Scale, see axis parameter 6) value.
minimum motor current:
0 – 1/2 of CS
1 – 1/4 of CS
0/1
RW
169
smartEnergy
current down
step
Sets the number of stallGuard2 readings above
the upper threshold necessary for each current
decrement of the motor current.
Number of stallGuard2 measurements per
decrement:
Scaling: 0… 3: 32, 8, 2, 1
0: slow decrement
3: fast decrement
0… 3
RW
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.
0… 15
RW
Hysteresis:
(smartEnergy hysteresis value + 1) * 32
Upper stallGuard2 threshold:
(smartEnergy hysteresis start + smartEnergy
hyst 1) * 32
171
smartEnergy
current up step
Sets the current increment step. The current
becomes incremented for each measured
stallGuard2 value below the lower threshold
(see smartEnergy hysteresis start).
current increment step size:
Scaling: 0… 3: 1, 2, 4, 8
0: slow increment
3: fast increment / fast reaction to rising load
1… 3
RW
172
smartEnergy
hysteresis start
The lower threshold for the stallGuard2™ value
(see smart Energy current up step).
0… 15
RW
173
stallGuard2 filter
enable
Enables the stallGuard2 filter for more precision
of the measurement. If set, reduces the
measurement 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
0/1

stallGuard2
threshold
This signed value controls stallGuard2
threshold
level for stall output and sets the
optimum measurement 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.
0 Indifferent value
1… 63 less sensitivity
-1
-64 higher sensitivity
-64… 63
