Why is the heatsink temperature of my Lenze ECSEA greater than +90 °C?
The heatsink temperature may be exceeding +90 °C because the ambient temperature is too high (Tu > +40 °C or > +50 °C), the heatsink is dirty, or the mounting position is incorrect. Allow the module to cool and ensure better ventilation. Clean the heatsink. Change the mounting position.
What to do if my Lenze Control Unit motor temperature is above +150 °C?
If the motor temperature exceeds the +150 °C threshold, it could be due to thermal overload from impermissible continuous current or frequent/long acceleration processes, or because no PTC/temperature contact is connected. Check the drive dimensioning and correct the wiring.
What to do if my Lenze ECSEA motor does not react to setpoint change?
If the motor isn't responding to setpoint changes, it might not be connected in the correct phase relation. Ensure the motor is correctly connected at terminals U, V, and W.
What to do if my Lenze ECSEA Control Unit motor rotates with Imax and half slip frequency?
If the motor rotates with Imax and half slip frequency, the motor might not be connected in the correct phase relation. Connect the motor in the correct phase relation at the terminals U, V, W.
What to do if my Lenze ECSEA motor temperature via inputs T1 and T2 is too high?
If the motor temperature is too high via inputs T1 and T2, it could be due to thermal overload from impermissible continuous current or frequent/long acceleration processes, or because terminals T1 and T2 are not connected. Check the drive dimensioning and connect the PTC/temperature contact.
Why does my Lenze Control Unit motor block in certain positions?
The motor might be blocking in certain positions because the number of pole pairs of the resolver or motor is not set correctly. Ensure the number of pole pairs (C0080) is correctly set.
How to correct a fault during parameter initialisation in Lenze ECSEA?
A fault during parameter initialization indicates an error during parameter set transfer between two controllers, or that the parameter set doesn't match the controller (e.g., data transmitted from a higher-performance controller to a lower-performance one). Correct the parameter set and check code initialization values.
What does it mean if C0060 counts down after controller enable on my Lenze Control Unit?
If C0060 counts down after controller enable, the rotor position indicated under C0060 is derived from the position encoder. Observe the mounting position when using separate feedback systems for position (C0490) and speed (C0495).
What to do if my Lenze Control Unit motor rotates CCW?
If the motor rotates counter-clockwise (CCW) when viewed from the motor shaft, the feedback system is not connected in the correct phase relation. Connect the feedback system in the correct phase relation.
