Additional Information

Setting activation parameter p3700
The individual bits of the activation parameter have the following significance:
p3700 bit Value Significance
0
1
2
3
8
9
Additional dependencies when using bit 3:
1)
• When using SINUMERIK, DSC and precontrol should be active.
• When using EPOS/position control, the standard connection must be
changed to:
– r2560 (output position controller) interconnected with: p1160
– r2561 (speed precontrol value) interconnected with: p1430
• The interpolator should be activated: p1400.7 = 1

8.14 Advanced Position Control (including Active Vibration Suppression)
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 highpass 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 accuracy.
0 –
1 The speed from the direct measuring system selected for APC, weighted with
p3702, and the motor speed are used as speed actual value for the speed control.
0 The actual encoder value selected with p3701 is used as the APC actual value.
1 Instead of the selected encoder value, the source of p3749 weighted with p3748 is
used.
If bit 1 or bit 2 are simultaneously set, then they change the acceleration compo-
nent (which goes through p3760/p3765) while the speed component (which goes
through p3761/p3766) is still taken from BICO.
