Bit 21: Message "External alarm" (H)
"External alarm"
♦ An "external alarm 1" is present in control word bit 28, or, "external
alarm 2" in control word bit 29.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
Bit 22: Message "Alarm i
2
t drive converter" (H)
Alarm "i
2
t alarm, inverter" (A025)
♦ If the instantaneous load status is maintained, then the drive
converter will be thermally overloaded.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
Bit 23: Message "Fault, converter overtemperature" (H)
"Inverter temperature too high" fault (F023)
♦ The limiting inverter temperature has been exceeded.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
Bit 24: Message "Alarm, converter overtemperature" (H)
Alarm, "inverter temperature too high" (A022)
♦ The inverter temperature threshold to release an alarm has been
exceeded.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
Bit 25: Message "Alarm, motor overtemperature" (H)
Alarm "Motor overtemperature"
♦ it involves an "I
2
t alarm, motor" (A029) or an overtemperature alarm
from the KTY (P380 > 1) or PTC thermistor (P380 = 1).
♦ The alarmis initiated either by calculating the motor load (r008 /
K0244) or from the KTY84 sensor (r009 / K0245).
♦ Parameters involved in the calculation:
P380 (mot. temp. alarm), P382 (motor cooling),
P383 (mot. temp.T1), P384 (mot. load limit).
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
