Cod. Name
EF EF Ext Fault It trips when External fault input is active 1 YES 0
OC OC OverCurrent It trips when an Overcurrent value is detected by output current sensor 2 YES 1
OU OV OverVoltage
It trips when the drive DC Bus voltage is higher than the maximun threshold for the
given main voltage setting
3 YES 2
UU UV UnderVoltage
It trips when the drive DC Bus voltage is lower than the maximun threshold for the
given main voltage setting
4 YES 3
OH OH OverTemperat
It trips when the drive heatsink temperature detected by the switch sensor exceeds its
threshold (*)
5 NO 4
OLi OLi Drive OL It trips when the drive overload accumulator exceeded the trip threshold 6 NO 5
OLM OLM Motor OL It trips when the motor overload accumulator exceeded the trip threshold 7 NO 6
OLr OLr Brake res OL
Its intervention occurs when the overload cycle of the external braking resistance
does not correspond to the dened limits.
8 NO 7
Ot Ot Inst OverTrq
It trips when the torque delivered by the motor exceeds the programmed level for the
preset time
9 NO 8
PH PH Phase loss
It trips when the supply phase lack: enabled 30 seconds after one of the supply
phases has been disconnected
10 NO 9
FU FU Fuse Blown It trips when the drive input fuses are blown 11 NO 10
OCH OCH Desat Alarm IGBT desaturation or instantaneous overcurrent have been detected 12 YES 11
St St Serial TO It trips when the serial link time out exceeds the programmed level (I.604 parameter) 13 YES 12
OP1 Reserved 14 NO 13
OP2
Reserved
15 NO 14
bF bF Bus Fault Drive comunication Bus failure 16 NO 15
OHS OHS OverTemperat It trips when the drive heatsink temperature exceeds a safety level. (*) 17 NO 16
SHC SHC Short Circ Short Circuit between output phases or Ground fault 18 NO 17
Ohr Riservato 19 18
Lf LF Limiter fault
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.
20 NO 19
PLC PLC Plc fault
"PLC program not active. Lift application does not function.
Run C.050 parameter to reset the alarm."
21 NO 20
EMS Key Em Stp fault Reserved 22 NO 21
UHS UHS Under Temperat
It trips when the temperature of the drive heatsink is below a safety level (typically
–10°C).
23 NO 22
PHO Phase Loss Output
See gure 7.2: it trips during the phase (2) if the current does not exceed the limit
dened
25 NO 24
*) OH switch sensor threshold and OHS analog sensor threshold depend on the drive size (75 °C ... 85 °C)
