What to do if braking energy is too high in Lenze ECSES?
If the Lenze Control Unit's braking energy is too high, resulting in the DC-bus voltage exceeding the value set in C0173, consider using a braking unit or regenerative module. Also, check the dimensioning of the brake resistance.
Why Lenze ECSES Control Unit motor does not follow the setpoint change?
If the Lenze Control Unit motor does not follow the setpoint change, it 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 there is a current overload of the axis module in Lenze ECSES?
If the Lenze Control Unit axis module experiences a current overload, such as due to frequent and prolonged acceleration processes or continuous overload with Imotor exceeding 1.05 x INx, check the drive dimensioning.
How to fix short circuit of motor cable in Lenze ECSES?
To resolve a short circuit in the Lenze Control Unit motor cable, search for the cause of the short circuit and check the motor cable. If the issue is excessive capacitive charging current, use a motor cable that is shorter or has lower capacitance.
What to do if DC-bus voltage is lower than specified in Lenze Control Unit?
If the DC-bus voltage is lower than specified under C0174 in your Lenze Control Unit, check the mains voltage and the power supply module.
What to do if motor is thermally overloaded in Lenze ECSES?
If the Lenze Control Unit motor is thermally overloaded due to impermissible continuous current or frequent/long acceleration processes, check the drive dimensioning and switch off monitoring (C0583 = 3).
What to do if motor cable earth fault in Lenze ECSES?
If the Lenze Control Unit motor cable has an earth fault, where one of the motor phases has earth contact, search for the cause of the short circuit and inspect the motor cable.
Why torque of synchronous motor is too low in Lenze ECSES?
If the torque of your Lenze Control Unit synchronous motor is too low, it could be due to an incorrect rotor angle (offset of electrical and mechanical rotor angle). Perform a rotor position adjustment (C0095 = 1) or manually set the rotor displacement angle. Operate the motor without load while doing this.
What to do if a current-carrying motor phase has failed in Lenze ECSES Control Unit?
If a current-carrying motor phase has failed in the Lenze Control Unit, check the motor and motor cable. You can also switch off monitoring (C0597 = 3). If the current limit value is set too low, set a higher current limit value via C0599.
What to do if there is a current overload of the axis module > C0123 in Lenze ECSES Control Unit?
If the Lenze Control Unit axis module experiences a current overload exceeding C0123, possibly due to frequent or prolonged acceleration phases, check the drive dimensioning and the setting of C0123.
