Number Axis parameter Description
Units / Default
Acc.
114
CL current scale
maximum
Maximum 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 motor driver chip
(see axis parameters 6)
The physical maximum current is defined
by the sense resistors and MOSFETs of the
TMCM-1311 and is limited to 3.0A RMS.
Default = 255
[1/256]
RW
115
CL current scale
input select
Current scaling using raw position error or
product of position error and gain factor
(depends on axis parameters 136 and 137).
0 = only raw position error used for current
scaling
1 = (position error * gain) used for current
scaling
0/1
Default = 1
RW
116
CL current scale
lower error
limit
Position error from which on the current
amplitude is increased (current scale factor is
increased).
Default = 0
[encoder steps]
RW
117
CL current scale
upper error
limit
Position error from which on the current
amplitude will be increased to its configured
maximum (parameter 114).
This parameter must be higher than axis
parameter 116.
Default = 255
[encoder steps]
RW
118
CL current scale
increment value
Current scale increment value if the actual
current scale factor is below the calculated
current scale factor target value.
This parameter defines the step width at which
the current scale factor will be increased.
Default = 1
[1/256]
RW
119
CL current scale
decrement
value
Current scale decrement value if the actual
current scale factor is higher than the
calculated current scale target value.
This parameter defines the step width at which
the current scale factor will be decreased.
Default = 1
[1/256]
RW
120
CL current scale
increment
timeout
This parameter defines the delay between two
current scale factor increments and thereby
controls the rate at which the current scale
factor will be increased.
Setting a timeout value here serves for
dampening and prevents from high
oscillations.
0 = the scale factor will directly be set to the
actual target value without delay.
Default = 1
