Description: Controlled reluctance motor:
Display of the lower torque limit to evaluate the optimum flux characteristic.
Above the optimum flux characteristic p2970ff, the value corresponds with the
lower flux limit p1581, and is referred to the rated motor torque.
Description: Controlled reluctance motor:
Scaling of the gradient limit of the flux when increasing up to the available residual voltage.
Note: The possible steepness (gradient) of the flux increase when torque is demanded is limited by the available residual
voltage. This parameter allows this limit to be scaled.
Description: Displays signals of the open-loop flux control of the closed-loop controlled reluctance motor.
Index: [0] = Setpoint before filter
[1] = Output MTPC characteristic
[2] = Lower limit at low torque
[3] = Lower limit at low speed
[4] = Upper limit from field weakening controller total
[5] = Upper limit from field weakening controller precontrol
Description: Sets the flux setpoint referred to rated motor flux.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
