Position controller output limited
The speed setpoint requested from the position controller lies above
the max. motor speed.
Possible causes:
– Programmed velocity (P0082:64) too high
– Max. acceleration (P0103) or deceleration (P0104) too high
– Axis is overloaded or blocked
– Check and correct the above parameter

parameterizable
Flux controller output limited
The specified flux setpoint cannot be realized, although maximum cur-
rent is input.
– Motor data are incorrect
– Motor data and motor connection type (star/delta) do not match
– Motor has stalled because motor data are extremely inaccurate
– Current limit is too low for the motor (0.9 * P1238 * P1103 < P1136)
– Power section is too small
– Correct the motor data
– If required use a larger power section
RESET FAULT MEMORY
parameterizable
Current controller output limited
The entered setpoint cannot be impressed in the motor, although the
maximum voltage has been entered. The cause could be that the motor
is not connected, or a phase is missing.
– Check the connecting cable, motor/drive converter (phase missing)
– Check the motor contactor
– DC link voltage present?
– Check the DC link busbar (check that the screws are tight)
– Use monitoring function in the power section has responded (RESET
by powering off/powering on)
– Replace the power section or control module
RESET FAULT MEMORY
parameterizable
Speed controller output limited
The speed controller is at its limit for an inadmissibly long time (torque
or current limit). The permissible time is defined in P1605, the upper
speed limit when the monitoring responds, in P1606.
Synchronous motor:
In correct operation, the correctly optimized axis drive should never
reach its current limit, not even with large speed changes (changing
from rapid traverse in the positive direction to rapid traverse in the neg-
ative direction).
P1605 = 200 ms
