6 Positioning mode
6.1 Function: Position control
In the positioning mode, the motor controller receives the positioning setpoint value(position/position
record number) via t he control interface (f ieldbus/digital inputs).
– In the direct, individual record, record linking, homing and jog modes, the point-to-point positioning
(trapezoidal speed curve) is calculated in the controller-internal positioning controller from the
positioning parameters and passed on as position/speed setpoint va lue s.
– In the case of interpolating positioning mode, the interpolated positioning curve is calculated in the
interpolator and passed on as position/speed setpoint values.
The regulator cascade (position, speed and current regulator) processes the deviation between set-
point value and actual value and thus controls the output stage and the connected motor.
