2.2 List of parameters
Description:
Displays the actual output of the Vdc controller (DC link voltage controller)
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description:
Sets the open and closed-loop control mode of a drive.
Value:
0:
U/f control with linear characteristic
1:
U/f control with linear characteristic and FCC
2:
U/f control with parabolic characteristic
3:
U/f control with parameterizable characteristic
4:
U/f control with linear characteristic and ECO
5:
U/f control for drives requiring a precise freq. (e.g. textiles)
6:
U/f control for drives requiring a precise frequency and FCC
7:
U/f control for a parabolic characteristic and ECO
19:
U/f control with independent voltage setpoint
20:
Speed control (encoderless)
21:
Speed control (with encoder)
22:
Torque control (encoderless)
23:
Torque control (with encoder)
Dependency:
For Standard Drive Control (p0096 = 1), settings p1300 = 0, 2 are possible, for Dynamic Drive Control (p0096 = 2)
only p1300 = 20, 21 can be set. Closed-loop speed or torque control (with encoder) cannot be selected if the encoder
type is not entered (p0400).
Operation with speed encoder is not possible for permanent-magnet synchronous motors.
Refer to: p0108, p0300, p0311, p0400, p1501
Notice:
Active slip compensation is required in the U/f control types with Eco mode (p1300 = 4, 7). The scaling of the slip
compensation (p1335) should be set so that the slip is completely compensated (generally 100%).
The Eco mode is only effective in steady-state operation and when the ramp-function generator is not bypassed. In
the case of analog setpoints, if required the tolerance for ramp-up and ramp-down should be actively increased for
the ramp-function generator using p1148 in order to reliably signal a steady-state condition.
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
displayed in r1407, bit 2 and bit 3.
