Alarm
Description
A039 I2t value of power section too high
(active in all operating states)
This alarm is activated if the permissible I2t value
for the relevant power section is reached. At the same time, the current limit is
set to P077 * 100% of the converter rated current. This limit is not cancelled again until the setpoint drops below 100% of the
converter rated current. See also Fault F039 and Parameter P075.
A044 An alarm is active on one slave connected to the paralleling interface [V2.1 and later]
(active in all operating states)
A046 Analog select input for main setpoint (terminals 4 and 5) faulty
(active in operating states of
≤
o6)
This alarm is activated when P700=2 (current input 4 to 20 mA) and the input current is less than 3mA.
A047 Analog select input 1 (terminals 6 and 7) faulty
(active in operating states of
≤
o6)
This alarm is activated when P710=2 (current input 4 to 20 mA) and the input current is less than 3mA.
A049 SCB1: No SCI slave connected
(active in all operating states)
A050 SCB1: Not all required SCI slaves are available
(active in all operating states)
The SCI slave required to perform the parameterized functions is not available
A053 Alarm message from free function block FB258
(active in all operating states)
The binector connected via parameter U106 Index.002 is in the log. "1" state
A054 Alarm message from free function block FB259
(active in all operating states)
The binector connected via parameter U107 Index.002 is in the log. "1" state
A067 Converter cooling faulty
(active in all operating states)
The heatsink temperature is > 90 °C.
The monitoring function is activated 6s after the electronics supply is connected.
(The current heat sink temperature is indicated at parameter r013 and on connector K050)
