protection
(2.7.12)
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to
3 = Fault, stop mode after fault always by coasting
Setting the parameter to 0 will deactivate the protection and reset the stall time counter.

Stall
current
limit
(2.7.13)
The current can be set to 0.0…2*I
H
. For a stall
stage to occur, the current must have exceeded
this limit. See Figure 20. The software does not
allow entering a greater value than 2*I
H
. If para-
meter
Nominal current limit of motor is
changed, this parameter is automatically calcu-
lated to 90% of the current limit.
