Drive Overheat Warning
Yaskawa · J1000 AC Drive
What does oH2 mean?
An external device has triggered an overheat warning signal, which was input to a multi-function input terminal (S1 through S8) configured for this purpose (H1- = B). This indicates an overheat condition originating from an external component connected to the drive. Failure to address the external overheat can lead to damage to that device or related process disruptions.
