2.2 List of parameters
Description: Sets the activation threshold for the brake chopper.
The hysteresis defines the range of the output voltage from zero up to the maximum voltage.
Index: [0] = Braking chopper threshold value
[1] = Braking chopper hysteresis
Dependency: Select operation with braking resistor: p1300 = 15
Refer to: p1360, r1363, p1364
Description: Displays the actual power unit output voltage (Motor Module) in braking chopper operation.
Dependency: Select operation with braking resistor: p1300 = 15
Refer to: p1360, p1362, p1364
Description: Sets the percentage value for the asymmetry detection for the braking chopper.
The ripple of the absolute current r0068 is monitored.
The reference value is the average value of the absolute current.
The minimum monitoring value is 10 % of the power unit rated current.
Dependency: Select operation with braking resistor: p1300 = 15
Refer to: p1360, p1362, r1363
Note: For p1364 = 0, dissymmetry identification is deactivated.
Asymmetry can also be displayed if the absolute current manifests ripple, caused by load-related ripple of the DC link
voltage. In this particular case, p1364 must be increased.
Description: Displays the measured actual phase currents as peak value.
This value is averaged for the display in the speed controller sampling time (p0115[1]).
