Parameter Descriptions
3.31.2 43-1* Power Card Status
This parameter group contains read-only information on
the power card status. All parameters in this group are
arrays:
•
[0]: Power card 1 (the master power card in a
parallel frequency converter, or the only power
card in a frequency converter with a single
inverter section).
•
[1]: Power card 2 (inverter connection in a parallel
frequency converter).
•
[2]: Power card 3 (inverter connection in a parallel
frequency converter).
•
[3]: Power card 4 (inverter connection in a parallel
frequency converter).
•
[4]: Power card 5 (rectifier connection in a parallel
frequency converter).
•
[5]: Power card 6 (rectifier connection in a parallel
frequency converter).
•
[6]: Power card 7 (rectifier connection in a parallel
frequency converter).
•
[7]: Power card 8 (rectifier connection in a parallel
frequency converter).

This parameter is valid for FC
302 only.
Shows the heat sink temperature at
the location of the phase W IGBT
power module. This measurement is
not available in all enclosure sizes.
Parameter 16-34 Heatsink Temp. uses
the value in this parameter.
Function:
NOTICE
[0 - 65535
RPM]
This parameter is valid for FC
302 only.
Shows the measured speed of fan A
on the power card. Each power
card has up to 3 fan connections.
Place the fan in the frequency
converter according to the
operating guide. A typical placement
for fan A is in the backchannel (the
external fan).
The value of this parameter is:
•
The actual fan speed
when there is a DC fan in
the frequency converter.
•
Relative speed when there
is an AC fan in the
frequency converter.
Function:
NOTICE
[0 - 65535
RPM]
This parameter is valid for FC
302 only.
Shows the measured speed of fan B
on the power card. Each power
card has up to 3 fan connections.
Place the fan in the frequency
converter according to the
operating guide. A typical placement
for fan B is on the enclosure door
(the internal fan).
The value of this parameter is:
