4: U/f control with linear characteristic and ECO
7: U/f control for a parabolic characteristic and ECO
20: Speed control (encoderless)
Dependency: For Standard Drive Control (p0096 = 1), settings p1300 = 0, 2 are possible, for Dynamic Drive Control (p0096 = 2) only
p1300 = 20 can be set.
Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).

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
For motors, type p0300 = 6 and 6xx, operation with U/f control is only recommended for diagnostic purposes.
