Quick stop ramp is only limited via maximum current 0x6073, maximum torque 0x6072 is not effective (corrected from V1.7.5)

Corrected from:
- i700 servo inverter  V01.07.05.10577

Response of the new version:
 
In the case of deceleration via quick stop (QSP) as fault response, both limitations are effective now:
  • Maximum current 0x6073 [%],  Reference value - rated motor current 0x6075 [A]
  • Maximum torque 0x6072 [%],   Reference value - rated motor torque 0x6076 [Nm]
 

What happens?
In the case of quick stop (QSP) as fault response, only the limitation via the maximum current 0x6073 is effective.
The limitation via the maximum torque 0x6072 is not effective for the QSP ramp.
 
When does the problem occur?
Always.
 
Which products are affected?
- i700 servo inverter ≤ V01.06.03.9953

Short-term measures/recommendations:
Limit the maximum permissible torque for the machine via the maximum current setting (0x6073) during the quick stop ramp.
 
Evaluation:
So far, it has also been possible to limit the torque in the case of quick stop. The setting via the maximum current is just not as convenient as when selecting the maximum torque.
