*) OH switch sensor threshold and OHS analog sensor threshold depend on the drive size (75 °C ... 85 °C)

It trips when External fault input is active
It trips when an Overcurrent value is detected by output current sensor
It trips when the drive DC Bus voltage is higher than the maximun threshold for
the given main voltage setting
It trips when the drive DC Bus voltage is lower than the maximun threshold for
the given main voltage setting
It trips when the drive heatsink temperature detected by the switch sensor
exceeds its threshold (*)
It trips when the drive overload accumulator exceeded the trip threshold
It trips when the motor overload accumulator exceeded the trip threshold
Its intervention occurs when the overload cycle of the external braking
resistance does not correspond to the defined limits.
It trips when the torque delivered by the motor exceeds the programmed level
for the preset time
It trips when the supply phase lack: enabled 30 seconds after one of the supply
phases has been disconnected
It trips when the drive input fuses are blown
IGBT desaturation or instantaneous overcurrent have been detected
It trips when the serial link time out exceeds the programmed level (I.604
parameter)
Communication failure between drive regulation board and option 1 expansion
board
Communication failure between drive regulation board and option 2 expansion
board
Drive comunication Bus failure
It trips when the drive heatsink temperature exceeds a safety level. (*)
Short Circuit between output phases or Ground fault
Reserved
It trips when the output current limiter or the DC-Link voltage limiter fail. The
failure can be caused by wrong settings of regulator gains or by the motor load.
PLC program not active. Lift application does not function.
Run C.050 parameter to reset the alarm.
Reserved
It trips when the temperature of the drive heatsink is below a safety level
(typically –5°C).
It trips in case of a power loss on the cable connecting the encoder to the
drive.
See figure 7.2: it trips during the phase (2) if the current does not exceed the
limit defined in parameter A.087.
