Additional dependencies when using bit 3:
1)
1. When using SINUMERIK, first activate the "DSC" and "Precontrol" functions.
2. When using the position controller function module, change the standard connection to:
3. Activate the interpolator: p1400.7 = 1.

9.14 Advanced Position Control (including Active Vibration Suppression)
Value Meaning
0 The value "0" is not applied to the speed setpoint.
This setting must be used to measure the filter frequency responses.
1 The acceleration filter output is applied to the speed setpoint.
The differential position feedback is activated.
0 The actual encoder value selected with p3701 is used as the APC speed actual value.
1 The source of p3750 is used as the APC acceleration actual value.
0 The actual encoder value selected with p3701 is used as the APC actual value.
1 A model value without sensor is used as the APC actual value on the load side. PT1
filtering with p3709 acts as smoothing time and a highpass filter with p3751 as a high‐
pass time constant. Bit 1 can be set but is not effective.
0 –
1 The setpoint acceleration of the axis is taken into account in the APC calculation. This
is especially relevant for applications that require a high contour precision.
0 Connecting the APC signal to the P component of the speed controller.
1 Connecting the APC signal to the P and I components of the speed controller.
0 –
1 The speed weighted with p3702 is used as speed actual value for the speed control. The
speed comprises the direct measuring system selected for APC and the motor speed.
0 The actual encoder value selected with p3701 is used as the APC actual value.
1 Instead of the selected encoder actual value, the source of p3749, weighted with p3748,
is used.
If bit1 or bit2 is simultaneously set, then these modify the acceleration component as a
result of p3760 to p3765, while the speed component is still taken from the BICO as a
result of p3761 to p3766.
