Status word
The status word contains 12 bits (bit 0… 11).
They can be read out using command GAP 18.
If a bit is set the specific event has occurred.

I²t limit
An actual I²t sum that exceeds this limit leads
to increasing the I²t exceed counter.

27
I²t sum
Actual sum of the I²t monitor.

I²t exceed
counter
Counts how often an I²t sum was higher than
the I²t limit.

Clear I²t
exceeded flag
Clear the flag that indicates that the I²t sum
has exceeded the I²t limit.

CL field
weakening
minimum
velocity
Minimum motor speed at which the speed
dependent Back EMF compensation will be
applied (field weakening).
Based on the velocity measured via encoder
feedback.

CL field
weakening
maximum
velocity
Maximum motor speed for the speed
dependent Back EMF compensation will be
applied (field weakening).
Based on the velocity measured via encoder
feedback.

CL encoder offset
Offset between encoder and electrical angle for
correction of possible misalignment.

113
CL current scale
minimum
Minimum current scale factor for current
regulation.
255 = 1 = 100% of maximum current
127 = 0.5 = 50% of maximum current
…
Attention!
The maximum current itself is defined by the
CS parameter of the motor driver chip (see axis
parameter 6)
Default = 15
