8.5.1.21 PNU 304, Target range
The parameter specifies the accuracy window (in mm/°). If the actual value of position is within the
range defined by this parameter, then a positioning movement is looked upon as being complete. If the
target range is chosen to be too small, then it is possible that a positioning order may not be
completed. The target range depends on Parameters 505 (encoder resolution), 1 (gearbox factor) and
2 (pitch). The default value is 0.01 mm/°.
8.5.1.22 PNU 305, Tracking distance
The maximum tracking distance defines the maximum permissible difference between the internal
setpoint and the current actual value of position in increments. A value “-1” means that the tracking
error monitoring is deactivated. Interpretation of the default value: 1024 encoder increments x 10
motor revolutions.
8.5.1.23 PNU 306, Max. temperature
Maximum permissible temperature of the electronics in °C.
8.5.1.24 PNU 307, Overcurrent
This parameter defines the maximum overcurrent in ampere. This current is allowed for a short time
when accelerating for 500 ms in order to overcome the break-free torque.
