2.7.12 Stall current limit ID710
The current can be set to 0.0 – I
nMotor
*2. For a stall stage to occur, the current must
have exceeded this limit. See Figure 9-20. The software does not allow entering a
greater value than I
nMotor
*2. If the parameter 2.1.9 Nominal current of motor is
changed, this parameter is automatically restored to the default value (I
nMotor
*1.3).
2.7.13 Stall time ID711
This time can be set between 1.0 and 120.0s.
This is the maximum time allowed for a stall event detection. The stall time is
counted by an internal up/down counter.
If the stall time counter value goes above this limit, the protection will cause a trip
(see Figure 9-21).
