r1547[0...1] Torque limit for speed controller output / M_max outp n_ctrl
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [Nm]
Description: Displays the torque limit to limit the speed controller output.
Index: [0] = Upper limit
[1] = Lower limit
r1548[0...1] Stall current limit, torque-generating, maximum / Isq_max stall
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [Aeff]
Description: Displays the limit for the torque-generating current component using the stall calculation, the current limit of the
motor module as well as the parameterization in p0640.
Index: [0] = Upper limit
[1] = Lower limit
p1570[0...n] CO: Flux setpoint / Flux setpoint
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
50.0 [%]
Description: Sets the flux setpoint referred to rated motor flux.
Note: For p1570 > 100 %, the flux setpoint increases as a function of the load from 100 % (no-load operation) to the set-
ting in p1570 (above rated motor torque).
p1574[0...n] Voltage reserve dynamic / U_reserve dyn
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0 [Veff]
Description: Sets a dynamic voltage reserve.
Note: Increasing the reserve reduces the steady-state maximum output voltage (r0071).
p1580[0...n] Efficiency optimization / Efficiency opt.
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0 [%]
Description: Sets the efficiency optimization. When optimizing the efficiency, the flux setpoint of the closed-loop control is
adapted as a function of the load.
For p1580 = 100 %, under no-load operating conditions, the flux setpoint is reduced to 50 % of the rated motor flux.
