709 Stall protection (2.6.13)
0 = No response
1 = Warning

3 = Fault, stop mode after fault always by coasting
Setting the parameter to 0 will deactivate the protection and reset the stall time counter.
See chapter 9.3.
710 Stall current limit (2.6.14)
The current can be set to 0.1…I
nMotor
*2. For a
stall stage to occur, the current must have
exceeded this limit. See Figure 25. The
software does not allow entering a greater
value than I
nMotor
*2. If parameter ID113
Nominal current of motor is changed, this
parameter is automatically restored to the
default value (I
