What to do if there is overvoltage in the Lenze Power Supply DC bus?
If the Lenze Power Supply DC-bus voltage exceeds 880 V due to excessive braking energy, consider using a braking unit or regenerative module. Also, verify the sizing of the brake resistor.
Why does my Lenze ECSEE012 Power Supply show I x t overload?
If your Lenze Power Supply shows an I x t overload, it is likely due to frequent and prolonged acceleration with overcurrent or continuous overload with Imains exceeding 1.05 x Ir. Review the dimensioning to resolve this issue.
What to do if there is a short circuit/overload of brake resistor or IGBT in Lenze ECSEE012?
If your Lenze Power Supply indicates a short circuit/overload of the brake resistor or IGBT, it could be due to a defective brake IGBT, a brake resistor with low resistance, or the absence of a connected brake resistor. Inspect the brake resistor and replace the device if necessary.
How to fix overload of internal brake resistor in Lenze Power Supply?
If the internal brake resistor of your Lenze Power Supply is overloaded, possibly from frequent or prolonged braking, or if OC6 monitoring is active while using an external brake resistor, consider using an external brake resistor. Alternatively, deactivate OC6 monitoring by setting C0579 = 3 when an external brake resistor is in use.
What causes mains phase failure in Lenze ECSEE012 Power Supply?
If your Lenze Power Supply experiences mains phase failure, it could be due to a missing mains phase, a non-sinusoidal mains supply, or voltage dips. Check the mains voltage. If voltage dips are the issue, reduce the charging current (C0022). For ECS axis modules, set charge relay function C0175 = 3.
How to troubleshoot short circuit in Lenze ECSEE012 DC bus?
If the Lenze Power Supply experiences a short circuit in the DC bus, identify and rectify the cause of the short circuit. Inspect the DC bus wiring for any issues.
What to do if there is earth fault in the Lenze ECSEE012 DC bus?
If your Lenze Power Supply shows an earth fault in the DC bus, it may be because one of the DC bus cables has earth contact or the DC-bus capacity is too low. Check the DC bus wiring and increase the capacity if needed.
What to do if the mains voltage is beyond the operating range for Lenze ECSEE012?
If the mains voltage is outside the range defined under C0173 for your Lenze Power Supply, check the mains voltage and adjust C0173 accordingly.
Why is there a load on the Lenze Power Supply DC bus during charging?
If there is a load on the Lenze Power Supply DC bus during charging, it could be due to power consumption of the DC bus while charging or the maximum charging current (C0022) being too low. Check the system control/wiring and increase the maximum charging current (C0022).
