7.6 Limit settings
7.6.1 Current limit handling
P2.6.1.1 Current limit ID107
This parameter determines the maximum motor current from the AC drive. The
parameter value range differs from size to size.
When the Current limit is changed the Stall current limit is internally calculated to 90%
of the current limit (if the Stall current limit is greater than the Current limit). When the
current limit is active the drive output frequency is reduced until current is below the set
limit.
In closed loop control, the current limit affects the torque producing current limit, not
total current. This can be changed in options group with the t
parameter.
In drive synch operation limiting is for average current of units.
P2.6.1.2 Scaling of current limit ID399
0 = Not used
1 = AI1
2 = AI2
3 = AI3
4 = AI4
5 = FB Limit Scaling ID46 Monitoring value
This signal will adjust the maximum motor current between 0 and the parameter Motor
Current Limit.
P2.6.3 Current Limit Kp 1451
P2.6.4 Current Limit Ki 1452
