Absolute max. current
(CS / Current Scale)
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.
The most important motor setting, since too high values might
cause motor damage!

7
Standby current
The current limit two seconds after the motor has stopped.
168
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
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
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
183
smartEnergy slow run current
Sets the motor current which is used below the threshold
speed. Please adjust the threshold speed with axis parameter
182.
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.
181
Stop on stall
Below this speed motor will not be stopped. Above this speed
motor will stop in case stallGuard2 load value reaches zero.
182
smartEnergy threshold speed Above this speed coolStep becomes enabled.
214
Power down delay
Standstill period before the current is changed down to
standby current. The standard value is 200 (value equates
2000msec).
