2 Parameters
2.2 List of parameters
p7035[0...n] Par_circuit circulating current control operating mode / I_cct_ctrl mode
VECTOR_G (Parallel) Can be changed: U, T
Data type: Integer16
P-Group: Modulation
Not for motor type: -
Min
0
Description: Sets the operating mode of the circulating current control.
The circulating current control ensures symmetrical distribution of the total currents to the individual converters.
Value: 0:
1:
Dependency: Circulating current control is not possible for separate, offset motor winding systems (p7003 = 2).
p7036[0...n] Par_circuit circulating current control proportional gain / Circ_I Kp
VECTOR_G (Parallel) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
0.00000 [ohm]
Description: Sets the proportional gain for the circulating current controller.
The parameter is pre-set to the cable resistance.
p7037[0...n] Par_circuit circulating current control integral time / I_circ Tn
VECTOR_G (Parallel) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
2.0
Description: Sets the integral time of the circulating current controller.
The parameter is referred to the current controller sampling time (p0115[0]).
Dependency: Refer to: p0115
p7038[0...n]

Par_circuit circulating current control limit / I_circ limit

VECTOR_G (Parallel) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
1 [%]
Description: Sets the limit of the circulating current controller output values.
The parameter is, depending on the phase, referred to the valve lockout times (p1828, p1829, p1830).
