Acc.
134
CL position
reached window
Window around the target position in which
the target position will be considered as being
reached. This value should be adjusted to the
application and the resolution of the encoder.
If the actual position is within the target
reached window for at least or longer than
defined by axis parameter 135, the
position_reached
flag will be set.

CL position
reached time
Minimum duration the motor must be within
the target reached window (axis parameter
134) before the position will be considered as
reached and
position_reached
flag will be set.

CL standstill
position error
gain
When the target position is reached, the
velocity regulation will be switched off and the
system is in a special standstill mode. In this
mode, the position is hold and maintained as
long as the position error is within the range
of the standstill error limit (axis parameter 138)
around the target position.
This parameter is a gain factor for the position
error used for position maintenance in
standstill mode.
A value of 20 typically provides good
results.
Higher values provide higher stiffness.
For values greater than 25 a dampening
factor > 0 (axis parameter 137) should be
used as well to prevent from oscillations.

dampening
factor
When the target position is reached, the
velocity regulation is switched off and the
system is in a standstill mode where the
position is hold and maintained as long as the
position error is within the range of the
standstill error limit (axis parameter 138)
around the target position. Parameter 137 is a
dampening factor to prevent from oscillations
when using a high proportional gain (axis
parameter 136).
When axis parameter 136 is between 10
and 20, this parameter can be 0.
For higher proportional gain, e.g., 30, a
dampening factor of 20 is a good starting
value.

138
CL standstill
position error
limit
When the target position is reached, the
position maintenance by the ramp generator is
switched off and the system is in a standstill
mode.
As long as the position error is within the
range around the target position defined by
axis parameter 138, the position maintenance
is done using parameter 136 and 137.
When the position error exceeds the range
defined by this parameter, the configured ramp
parameters are used to move back to the target
position (as in normal positioning mode).
