coolStep Adjustment Points and Thresholds
Number
Axis Parameter
Description
I6
Absolute maximum current
The maximum value is 255.
This value
means 100% of the maximum current of the
module. The current adjustment is within
the range 0. . . 255 and can be adjusted in 32
steps (0. . . 255 divided by eight; e.g. step 0 =
0. . . 7, step 1 = 8. . . 15 and so on).
Too high values may cause motor damage!
I7
Standby current
The current limit two seconds after the mo-
tor has stopped.
I168
smartEnergy current minimum
Sets the lower motor current limit for cool-
Step 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
I169
smartEnergy current down step
Sets the number of stallGuard2 readings
above the upper threshold necessary for
each current decrement of the motor cur-
rent. Number of stallGuard2 measurements
per decrement:
Scaling: 0. . . 3: 32, 8, 2, 1
0: slow decrement
3: fast decrement
I171
smartEnergy current up step
Sets the current increment step.
The
current becomes incremented for each
measured stallGuard2 value below the
lower threshold (see smartEnergy hystere-
sis start).
current increment step size:
Scaling: 0. . . 3: 1, 2, 4, 8
0: slow increment
3: fast increment
SG170
smartEnergy hysteresis
Sets the distance between the lower and
the upper threshold for stallGuard2 read-
ing. Above the upper threshold the motor
current becomes decreased.
SG181
Stop on stall
Below this speed motor will not be stopped.
Above this speed motor will stop in case
stallGuard2 load value reaches zero.
V182
smartEnergy threshold speed
Above this speed coolStep becomes en-
abled.
T214
Power down delay
Standstill period before the current is
changed down to standby current. The stan-
dard value is 200 (which means 2000msec).
