P6.1.6
ab
Stall protection
ID 313
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = No action;
1 = Warning;
2 = Fault; or
3 = Fault, coast.
Description:
Stall protection is a user defined of overcurrent protection. It protects the motor from short time overload situations like a stalled shaft.
This is customer selectable based off of current level, frequency level, and time.
P6.1.7
b
Stall current limit
ID 314
Minimum value:
0.10 A
Maximum value:
2 * MotorNomCurr A
Default value:
1.3 * MotoNomCurr A
Description:
The current can be set to 0.1–InMotor*2. For a stall stage to occur, the current must have exceeded this limit.
The software does not allow entering a greater value than InMotor*2. If P1.6, nominal motor current is changed, this parameter is
automatically restored to the default value (IL).
P6.1.8
b
Stall time limit
ID 315
Minimum value:
1.0 s
Maximum value:
120.0 s
Default value:
15.0 s
Description:
This time can be set between 1.0 and 120.0s. This is the maximum time allowed for a stall stage. The stall time is counted by an
internal up/down counter based off the current being above the limit setting. If the stall time counter value goes above this limit the
protection will cause a trip (see P6.1.6).
P6.1.9
b
Stall frequency limit
ID 316
Minimum value:
1.00 Hz
Maximum value:
MaxFreq Hz
Default value:
25.00 Hz
Description:
The frequency can be set between 1–fmax (P1.2). For a stall state to occur, the output frequency must have remained below this limit,
above the current limit for the stall time to occur.
