When the position control loop is closed the drive monitors whether it can
follow the preset position command value. To do this a actual model
position value is calculated in the drive and compared with the real actual
position value. If the difference of calculated and real actual position value
exceeds the value entered in parameter
S-0-0159, Monitoring window
it
is obvious that the drive cannot follow the preset command value and the
error F2028 is generated.
Note:
The maximum deviation between calculated and real actual
position value can be read from
P-0-0098, Max. model
deviation
.
Cause
Remedy
Parameterized monitoring window too small
Check and, if necessary, correct content of
S-0-0159,
Monitoring window
Too high command acceleration due to incorrect
command value set by control unit
Reduce acceleration value set by the control unit (see
control unit manual)
Numeric value in
S-0-0092, Bipolar torque/force
limit value
too low
Check content of parameter
S-0-0092, Bipolar
torque/force limit value
and set it to maximum value
allowed for application
Axis is blocked or sluggish
Check mechanical system and remove axis blocking
Incorrect or non-optimized control loop parameters
Check control loop setting (e. g.
S-0-0104, Position
loop Kv-factor
,
S-0-0100, Velocity loop proportional
gain
,
P-0-0556, Control word of axis controller
)
Acceleration capacity of drive was exceeded
Check drive dimensioning
