Heatsink
Heatsink temperature of the converter is too high
This alarm always initiates the disconnection of the device 10 seconds after the failure
has been detected (Latch=ON).
An external controller (PLC,etc.) can read the alarm via programmable output, RS485
or Bus and it can execute a controlled stop within a 10 second delay.
Overtemp motor
Motor temperature (connection for thermistor:terminals 78 and 79).
External Fault
External fault (no voltage on terminal 15)
Brake fault
(See chapter 6.14.8) The converter was unable to complete the transient phase between
the start command and the release mechanical brake command within the time limit set
in the Torque Delay parameter.
The mechanical brake feedback (Brake fbk) was not received within the time allowed.
The mechanical brake feedback (Brake fbk) remains for 1 second after the close brake
command has been sent.
Motor I2t ovrld
If the
Motor
I2t accumulator
parameter reaches 100% the relative alarm is signalled.
Drive I2t ovrld
If the
Drive
I2t accumulator
parameter reaches 100% the relative alarm is signalled.
Overcurrent
Overcurrent (short-circuit / earth fault). The intervention point is determined by the
Overcurrent thr
parameter. This can also be used as indication of threshold overpass
for system applications.
Field loss
Too low field current. The intervention point corresponds to 50% of the min. field cur
-
rent set with the
Flux current min
parameter. This alarm message is active with the
enabled converter (
Enable
drive=Enabled).
Delta frequency
This alarm condition is active if the frequency of the three-phase power supply to the
drive exceeds the positive or negative percentage threshold set via the
Delta freq thres
parameter. The power supply frequency (50 or 60 Hz) and thus the relative thresholds are
automatically calculated by the drive as soon as the three-phase power supply is available.
SSC error
Functionality available starting from Firmware Standard=10.08A (TPD32-EV).
Threshold
parameter: thru this parameter is possible to set the number of consecutive
wrong data received through the fiber optical cable without generating an SSC Error.
The alarm cause reaction of the drive. A warning message can be output via a digital
output. When the drive is disabled, it will not restart until the failure has been cancelled.
Speed fbk loss
No speed feedback available.
When Activity=Warning in the CONFIGURATION /Speed fbk menu is chosen, the
Enable fbk bypass
parameter has to be set as “Enabled”, otherwise the drive reaches
an uncontrolled speed which can not be stopped.
Opt2 failure
Failure on the card “Option 2” (optional).
Bus loss
Failure in the connection on the field bus (only in connection with an option card of
bus interface).
SCR test
SCR test. This function detects the status of the drive’s SCR modules, if working cor
-
rectly, in short circuit and/or open.
n

!
The SCR test cannot be used for the TPD32-EV-FC and TPD32-EV series in 12-pulse configura
