What to do if Parker DC Drives inverter will not run?
- MMelissa CraigAug 11, 2025
If the Parker DC Drives inverter doesn't run when a start command is given, it could be due to several reasons: * **STO is invoked:** In this case, connect STOA and STOB to a 24Vdc supply, when it is safe to do so. * **STO Fault Latch may have tripped:** Remove all power from the inverter before re-applying. If the problem continues, return the inverter for repair. * **Inverter has tripped, but not due to STO:** Reset the trip and eliminate the cause. If the issue persists, return the inverter for repair. * **Faulty Hardware:** Return the inverter for repair.
