braking resistor data
Parameter structure for displaying the power at the
braking resistor
Sub Idx
Name
Function
1
rated resistance at 20°C
Resistance value of the braking resistor
2
average dissipated power
average absorbed power of the braking resistor
Change of the time constant:
previous softwares: PT1 time = 4.3 min
new time constant: 2 minutes
3
current electrical resistance
Only for sub-mounted braking resistor:
Actual electrical resistance from the temperature
model.
Display when the power unit is not ready:
4294967295: power unit not ready
Without sub-mounted braking resistor identcal with
is31[1]
4
current wire temperature
Actual wire temperature in 0.1 °C resolution
Display if no temperature model is available: -1000:
no temperature available
Display when the power unit is not ready:
32767: power unit not ready
5
peak wire temperature
For sub-mounted braking resistor:
Maximum wire temperature in 0.1 °C resolution
Without sub-mounted braking resistor:
Display -1000: no temperature available
6
peak power over braking
resistor
Maximum power at the braking resistor
(maximum value of is31[9], stored non-volatile)
7
error resistor data
0: Data for sub-mounted braking resistor OK
All other values: invalid sub-mounted braking resistor
data
8
cumulated energy over
braking resistor
cumulated energy over braking resistor
(resolution: 0.01 kWh)
The value can be reset / set to any value by writing to
the parameter.
9
current power over braking
resistor
Actual power flowing into the braking resistor. The fil-
ter time is calculated from the basic process time
(see description is22)
Filter time without sub-mounted braking resistor: TFil-
ter = 48 * basic Tp
(at Tp = 62.5us TFilter is = 48 * 62.5us = 3ms)
Filter time with sub-mounted braking resistor: TFilter
= 64 * basic Tp
