Parameters 213
48.02
Bc run-time ena
Selects the source for quick run-time brake chopper control.
0 = Brake chopper IGBT pulses are cut off
1 = Normal brake chopper IGBT modulation. The overvoltage
control is automatically switched off
This parameter can be used to program the chopper control
to function only when the drive is operating in the generator
mode.
Const
Bit pointer setting (see
on page
). -
Pointer
48.03
BrThermTimeConst Defines the thermal time constant of the brake resistor for
overload protection.
0 … 10000 s
Brake resistor thermal time constant.
1 = 1 s
48.04
Br power max cnt
Defines the maximum continuous braking power which will
raise the resistor temperature to the maximum allowed value.
The value is used in the overload protection.
0.0000 …
10000.0000 kW
Maximum continuous braking power.
10000 =
1 kW
48.05
R br
Defines the resistance value of the brake resistor. The value
is used for brake chopper protection.
0.1000 …
1000.0000 ohm
Brake resistor resistance value.
10000 =
1 ohm
48.06
Br temp faultlim
Selects the fault limit for the brake resistor temperature
supervision. The value is given in percent of the temperature
the resistor reaches when loaded with the power defined by
parameter
.
When the limit is exceeded the drive trips on fault BR
OVERHEAT.
0 … 150%
Brake resistor temperature fault limit.
1 = 1%
48.07
Br temp alarmlim
Selects the alarm limit for the brake resistor temperature
supervision. The value is given in percent of the temperature
the resistor reaches when loaded with the power defined by
parameter
.
When the limit is exceeded, the drive generates a BR
OVERHEAT alarm.
0 … 150%
Brake resistor temperature alarm limit.
1 = 1%
49
49 Data storage
Data storage parameters reserved for the user. These
parameters can be written to and read from using other
parameters’ pointer settings.
Four 16-bit and four 32-bit storage parameters are available.
49.01
Data storage1
Data storage parameter 1.
-32768 … 32767
16-bit data.
1 = 1
49.02
Data storage2
Data storage parameter 2.
-32768 … 32767
16-bit data.
1 = 1
49.03
Data storage3
Data storage parameter 3.
-32768 … 32767
16-bit data.
1 = 1
49.04
Data storage4
Data storage parameter 4.
-32768 … 32767
16-bit data.
1 = 1
No.
