constant current limit
Inverter state ru.00
Actual frequency ru.03
act. utilization ru.13
In the operating modes positioning or synchronous running, this function is not active. If a quick stop ramp time
is entered in Pn.60 for abnormal stopping, the deceleration stop is active.
Current-dependent ramp stop
In v/f-characteristic operation, overcurrent errors can occur due to short ramps.
Therefore, a current limit can be programmed with Pn.24 "LAD load level" that is hold on exceeding the ramp
generator output value (ru.02).
In closed-loop operation the current is limited in software by the control-internal current and torque limits.
Therefore the functions acceleration stop (LA-Stop) and current-dependent deceleration stop (LD-Stop (I)) are
useless.
Pn.25: LAD load level

Explanation
0 .. 200%
Current level at which the ramp is stopped
If the acceleration stop in speed-controlled operation is active in order to use the interruption of the ramp via
digital input, the current level in Pn.25 must be set to 200% to avoid negative effects.
