Parameters 313
Selects the source for quick brake chopper on/off control.
0 = Brake chopper IGBT pulses are cut off
1 = Normal brake chopper IGBT modulation allowed.
This parameter can be used to enable chopper operation only
when the supply is missing from a drive with a regenerative
supply unit.

Defines the thermal time constant for the brake resistor
thermal model.
0 s
0…10000 s
Brake resistor thermal time constant, ie the rated time to
achieve 63% temperature.
1 = 1 s
Defines the maximum continuous load of the brake resistor
that will eventually raise the resistor temperature to the
maximum allowed value (= continuous heat dissipation
capacity of the resistor in kW) but not above it. The value is
used in the resistor overload protection based on the thermal
model. See parameter
the
data sheet of the brake resistor used.
0.00 kW
0.00…
10000.00 kW
Maximum continuous load of the brake resistor.
1 = 1 kW
Defines the resistance value of the brake resistor. The value
is used for the brake resistor protection based on the thermal
model. See parameter
0.0 ohm
0.0…1000.0 ohm
Brake resistor resistance value.
1 = 1 ohm
Selects the fault limit for the brake resistor protection based
on the thermal model. See parameter
. When the limit is exceeded, the drive trips on fault
.
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
.
105%
0…150%
Brake resistor temperature fault limit.
1 = 1%
Selects the warning limit for the brake resistor protection
based on the thermal model. See parameter
. When the limit is exceeded, the drive
generates a
warning.
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
.
95%
0…150%
Brake resistor temperature warning limit.
1 = 1%
No.
