Lenze · i550 Protec Drive
This warning occurs when a negative setpoint is selected with an active limitation of rotation (parameter 0x283A (P304.00)), or if the 'Reverse rotational direction' function (parameter 0x2631:013 (P400.13)) is requested while rotation limitation (parameter 0x283A (P304.00)) is active. The motor will be brought to a standstill because reversal of the rotating direction is not permissible under these conditions.
Click steps to track your progress.
Verify the current speed setpoint (e.g., via HMI, fieldbus monitor) and its polarity (e.g., -100 RPM).
Examine Parameter 0x283A (P304.00) to confirm if a rotation limitation (e.g., 'Forward Only') is enabled.
Check the state of the 'Reverse rotational direction' function (Parameter 0x2631:013) to see if it is active.
Adjust the speed setpoint to be positive if unidirectional forward rotation is intended, or disable the rotation limitation in Parameter 0x283A (P304.00).
Review the PLC or master control program to ensure speed commands and direction signals are consistent with the drive's desired operation mode.
