Description
Range [Unit]
7
standby current
The current limit two seconds after the motor
has stopped.
0… 255
8
target pos.
reached
Indicates that the actual position equals the
target position.
0/1
9
ref. switch status
The logical state of the reference (left) switch.
See the TMC 428 data sheet for the different
switch modes. The default has two switch
modes: the left switch as the reference
switch, the right switch as a limit (stop)
switch.
0/1
10
right limit switch
status
The logical state of the (right) limit switch.
0/1
11
left limit switch
status
The logical state of the left limit switch (in
three switch mode)
0/1
12
right limit switch
disable
If set, deactivates the stop function of the
right switch
0/1
13
left limit switch
disable
Deactivates the stop function of the left
switch resp. reference switch if set.

minimum speed
Should always be set 1 to ensure exact
reaching of the target position. Do not
change!
0… 2047
135
actual
acceleration
The current acceleration (read only).
0… 2047*
138
ramp mode
Automatically set when using ROR, ROL, MST
and MVP.
0: position mode. Steps are generated, when
the parameters actual position and target
position differ. Trapezoidal speed ramps are
provided.
2: velocity mode. The motor will run
continuously and the speed will be changed
with constant (maximum) acceleration, if the
parameter target speed is changed.
For special purposes, the soft mode (value 1)
with exponential decrease of speed can be
selected.

For three-switch mode: a position range,
where an additional switch (connected to the
REFL input) won't cause motor stop.

soft stop flag
If cleared, the motor will stop immediately
(disregarding motor limits), when the
reference or limit switch is hit.

ramp divisor
The exponent of the scaling factor for the
ramp generator- should be de/incremented
carefully (in steps of one).
