| Data type: | REAL |
Description:
Runtime error if the maximum permissible (measurable) phase current is exceeded in phase U or phase V.
The current limit depends on the ACOPOS module:

Reaction:
See error number 6019.
Cause/Remedy:
Set current value jump:
A jump in the set stator current of the quadrature component ICTRL_ISQ_REF occurs due to:
- Jump in the set position or set speed: See error number 5036.
- Jump in the encoder position or speed: See error number 4014.
- Jump in the speed offset (SCTRL_ADD_SET_PARID, SCTRL_SPEED_REF, SCTRL_V_SET_UNITS)
- Jump in the load offsets (ICTRL_ADD_SET_PARID, ICTRL_ADD_TRQ)
- Jump in the load on the motor shaft (jammed mechanics, load thrusts, etc.)
The actual stator current of the quadrature component ICTRL_ISQ_ACT can fluctuate above the maximum value as a result of a rigidly set current controller and a jump in the set stator current of the quadrature component ICTRL_ISQ_REF to the maximum value.
Unstable current controller:
- Due to magnetic saturation, the inductance is lower at high currents. The current controller is initialized automatically according to the motor inductance MOTOR_STATOR_INDUCTANCE. -> Check the current controller with the maximum permissible current.
- Incorrect current controller configurations: The current controller is initialized automatically according to the motor parameters MOTOR_STATOR_INDUCTANCE, MOTOR_ROTOR_INDUCTANCE. Check these parameters. -> Check the overshoot behavior of the step-response on the current controller.
