What to do if Lenze DC Drives show a short-circuit or overload?
- S
  Samantha WhiteAug 25, 2025
  If the Lenze DC Drives indicate a short-circuit or overload, the cause may be a short-circuit. You should find the reason for the short-circuit and check the motor cable. It can also be caused by excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current. If the acceleration time is too short, increase the acceleration time and check the controller selection. Also, check wiring if the motor cable is defective and check the motor for internal faults. If there is frequent and long overload, check the controller selection.

How to resolve Lenze ESMD153L4TXA stop with inhibited outputs?
- I
  ibarrettSep 2, 2025
  If the Lenze Inverter stops and the outputs U, V, W are inhibited, it is because there is a LOW signal at terminal 28. To solve this, set terminal 28 to HIGH.

Why is Lenze ESMD153L4TXA Inverter output frequency 0 Hz?
- T
  Tammy AndersonSep 4, 2025
  If the Lenze Inverter's output frequency is 0 Hz and the outputs U, V, W are inhibited, it could be due to: * Setpoint = 0 Hz (C31 = 0): In this case, you need to perform a setpoint selection. * Quick stop activated through digital input or serial link: Deactivate the Quick stop.

How to fix No access to code on Lenze ESMD153L4TXA?
- M
  Michele WangSep 7, 2025
  If the Lenze Inverter displays 'No access to code', it means that changes can only be made when the controller is in OFF or 1nh. To proceed, set terminal 28 to LOW or inhibit by serial link.
