Description: Sets the scaling of the stall limit for the start of field weakening.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Danger: If the stall current limit is increased, then the q current setpoint can exceed the stall limit; as a consequence, a
hysteresis effect can occur when loading and unloading.
Description: Sets the signal source for the scaling of the lower torque limiting to limit the speed controller output without taking into
account the current and power limits.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description: The following applies for a synchronous reluctance motor:
Displays the transition value for the start of the evaluation of the optimum flux characteristic.
The value is referred to the rated motor torque.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The transition value corresponds with the lower limit of the flux setpoint (p1581).
For a lower absolute torque setpoint, the flux setpoint remains at the lower limit (p1581).
Description: The following applies for a synchronous reluctance motor:
Sets the scaling of the rate time Tv for dynamic flux increase when the torque is quickly established.
The value is referred to the inverse value of the rated motor frequency.
Tv = p1567 / 100 % / p0310
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1401
Note: The "Dynamic load-dependent flux boost" function can be deactivated using p1401.9 = 0.
