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: Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
Operation with speed controller is not possible for permanent-magnet synchronous motors.
Refer to: 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 dis-
played in r1407, bit 2 and bit 3.
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

Description: Sets the configuration for the U/f control.
Note: Re bit 03:
When the bit is set, when the drive stops, the starting frequency of the motor holding brake is also not fallen below
when the actual slip frequency is less than the starting frequency.
