7222: Inverter: Summation current: Overcurrent

Info: Limit
Data type: REAL

Description:
Runtime error if the absolute value of the summation current (= |VCTRL_I0| = |VCTRL_I1 + VCTRL_I2 + VCTRL_I3|) exceeds the module-dependent limit VCTRL_I0_LIM (see info):

Reaction:
See error number 7224.

Cause/Remedy:
Ground is connected to the inverter output on contact U, V or W

Capacitive load: When using long motor cable (> 50m) or cable form third-party manufacturer.

Unstable current controller: See error number 9300.
-> In situations with high currents and high current change rates, dynamic current transformer errors can cause the measured summation current value to be too high.
