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: Only by selecting closed-loop speed control (p1300 = 20) is it possible to change over in operation to closed-loop
torque 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.
For the open-loop control modes p1300 = 5 and 6 (textile sector), slip compensation p1335, resonance damping
p1338, and the Imax frequency controller are switched off internally so that the output frequency can be set precisely.
The Imax voltage controller remains active.
During operation (pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing over
drive data sets.
Description: Sets the configuration for the U/f control.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note: For 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.
Description: Sets the configuration for the U/f control.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note: For 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.
For bit 04:
Field orientation for the closed-loop control of the basis application. The field orientation is activated with the
automatic calculation if p0096 is set = 1.
For bit 05 (only effective for p1302.4 = 1):
The starting current when accelerating (p1311) generally results in an increase in the absolute current and flux. With
p1302.5 = 1 the current is only increased in the direction of the load. This setting is recommended for drives with
higher power ratings or drives with extremely fast rates of acceleration.
For bit 07:
For field orientation (bit04 = 1), the Iq,max controller supports the current limiting controller (see p1341). For
diagnostic purposes, the Iq,max controller can be de-activated using this bit.
