The hardware current limit is an additional, fast protection to prevent faults caused by
overcurrent. Upon exceeding the max. short-time current limit (see Power Circuit
Instruction Manual) the hardware current limit becomes active. The following settings
are possible with uF.15:
0 off; Hardware current limit disabled
1 Single phase mode; Hardware current limit enabled; works both in motoric
and generatoric operation
2 Zero vektor mode; Hardware current limit enabled; works only motoric, but at
activated function it makes available more torque. Generatoric operation
switches to Mode 1.
The hardware current limit limits the current at the limit and triggers no error. This can lead to torque
breakdowns at the motor shaft, which is especially important during the operation „lifting and lowering"
since the drive can sag because of missing torque without the brake engaging.
