How to troubleshoot Lenze SMVector Inverter External fault?
If the Lenze Inverter displays an External fault because P121…P124 = 21 and that digital input has been opened, or P121…P124 = 22 and that digital input has been closed, correct the external fault condition and ensure the digital input is set properly for NC or NO circuit.
What to do if Lenze SMVector Inverter Control Configuration Fault?
If the Lenze Inverter is setup for REMOTE KEYPAD control (P100=2 or 5) but is not setup to communicate with a remote keypad, set P400 = 1, or P600 = 1. If the drive is setup for NETWORK ONLY control (P100=3) but is not setup for network communications, set P400 or P600 to a valid network communications protocol selection.
How to fix Lenze SMVector Inverter Drive ID warning?
If the Lenze Inverter is showing a Drive ID warning because the Drive ID (P502) stored on the EPM does not match the drive model, verify the motor data (P302…P306) and perform Auto Calibration. You can also set the drive mode (P300) to 0 or 1, reset the drive (P199 to 3 or 4), and reprogram it.
What causes Lenze SMVector Fast Current Limit?
If the Lenze Inverter is showing a Fast Current Limit due to overload, verify the drive/motor are the proper size for the application.
How to solve Lenze SMVector Inverter Current Limit (P171) reached?
If the Lenze Inverter is showing a Current Limit (P171) has been reached due to motor overload, increase P171 and verify the drive/motor are the proper size for the application.
What to do if Lenze SMVector Inverter OEM Defaults data fault?
If the Lenze Inverter drive is powered up with P199 = 1 and the OEM settings in the EPM are not valid, install an EPM containing valid OEM Defaults data or change P199 to 0.
How to fix Lenze SMVector Inverter Dynamic Braking fault?
If the Lenze Inverter dynamic braking resistors are overheating, increase the active deceleration time (P105, P126, P127) and check the mains voltage and P107.
Why Lenze SMVector Decel Override?
If the Lenze Inverter has stopped decelerating to avoid tripping into fault due to excessive motor regen (2 sec max), and it trips into fault, increase P105 and P126. Alternatively, install a Dynamic Braking option.
