Description: Sets the response for the Vdc_min controller (kinetic buffering).
Values: 0: Buffer Vdc until undervoltage, n<p1297 -> F07405
1:
Buff. Vdc until undervolt., n<p1297 -> F07405, t>p1295 -> F07406
Description: Sets the speed threshold for the Vdc-min controller (kinetic buffering). If this value is exceeded a fault is output; the
required response can be parameterized .
Description: Displays the actual output of the Vdc controller (DC link voltage controller)
Description: Sets the open and closed loop control mode of a drive.
Values: 20: Speed control (sensorless)
21: Speed control (with encoder)
23: Torque control (with encoder)
Dependency: Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
Refer to: p0108, r0108, p0300, p0311, p0400, p1501
Note: The closed-loop torque control can only be changed over in operation (p1300 = 20, 21) by selecting the closed-loop
speed control (p1501). At the changeover, the setting of p1300 does not change. In this case, the actual state is dis-
played in r1407, bit 2 and bit 3.
For sensorless operation (p1404 = 0 or p1300 = 20), the following applies:
- The following condition must be fulfilled: p1800 >= n / (2 * p0115[0]), n = 1, 2, ...
- For motors with a small power rating (< 300 W) we recommend to set n >= 2.
