List Manual, 09/2017, A5E33842890
Description:
Sets the configuration for the U/f control.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Notice:
p1302 bit 5 = 1: (only for field orientation p1302 bit 4 = 1)
This setting is only selected for very fast acceleration.
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 application class Standard Drive Control (p0096 = 1). 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. p1302.5 - in conjunction with p1310 and p1311
- are decisive when it comes to defining the quality of the starting response.
For bit 07:
For field orientation (bit04 = 1), an Iq,max controller supports the current limiting controller (see p1341). Inhibiting the
integral component can prevent the drive from stalling under overload conditions.
For bit 08:
Taking into account the saturation characteristic can be activated to improve faster starting operations for high-rating
motors.
For bit 09:
For field orientation (bit04 = 1), while the induction motor is being magnetized, the current is automatically increased
if the magnetization time p0346 is shortened.
