03.30 LIMIT WORD INV
The LIMIT WORD INV Word includes faults and warnings which occur when the
output current limit of the drive is exceeded. The current limit protects the drive in
various cases, for example, in case of integrator overload, high IGBT temperature,
etc.

Bit Name Description
0 INTEGRAT 200 Current limit at 200% integrator overload. Temperature
model is not active.*
1 INTEGRAT 150 Current limit at 150% integrator overload. Temperature
model is not active.*
2 INT LOW FREQ Current limit at high IGBT temperature with low output
frequency (<10 Hz). Temperature model is not active.*
3 INTG PP TEMP Current limit at high IGBT temperature. Temperature model
is not active.*
4 PP OVER TEMP Current limit at high IGBT temperature. Temperature model
is active.
5 PP OVERLOAD Current limit at high IGBT junction to case temperature.
Temperature model is active.
If the IGBT junction to case temperature continues to rise in
spite of the current limitation, the PP OVERLOAD alarm or
fault occurs. See chapter
Fault tracing .
6 INV POW LIM Current limit at inverter output power limit.
7 INV TRIP CUR Current limit at inverter overcurrent trip limit.
8 OVERLOAD CUR Maximum inverter overload current limit. See par. 20.03 .
9 CONT DC CUR Continuous dc-current limit.
10 CONT OUT CUR Continuous output current limit (I
cont.max
).
