A101 101 Off2ViaDI
Off2 (Emergency Off / Coast stop) pending via digital
input - start inhibition:
There is no problem with the drive itself! Check:
−
Off2 (10.08), if necessary invert the signal (group 10)

A102 102 Off3ViaDI
Off3 (E-stop) pending via digital input:
There is no problem with the drive itself! Check:

A103 103 DC BreakAck DC-Breaker acknowledge missing:
α
is set to 150° and single firing pulses are given, thus the
drive cannot be started or re-started while the DC-breaker
acknowledge is missing. Check:
−
DC BreakAck (10.23), if necessary invert the signal

ConvOverTemp
Converter overtemperature:
Wait until the converter is cooled down. Shutdown
temperature see MaxBridgeTemp (4.17). The converter
overtemperature alarm will already appear at
approximately 5°C below the shutdown temperature.
Check:
−
FanDly (21.14)
−
converter cover missing
−
converter fan supply voltage
−
converter fan direction of rotation
−
converter fan components
−
converter cooling air inlet (e.g. filter)
−
converter cooling air outlet
−
ambient temperature
−
inadmissible load cycle
−
connector X12 on SDCS-CON-F
