Function of thecurrent limit
Picture 7.13.8.1 Function of the current limit at constant run (default setting)
adjusted
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
Value
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.
