Inverter OverTemperature is triggered if heat sink or chip junction temperatures exceed warning levels, prompting reduced pulse frequency. The manual's first action is: “- Ambient temperature must lie within specified limits - Load conditions and load steps must be appropriate - Fan must turn when drive is running”

- Warning code
- Source
- Manual p. 392
What A00504 means
Inverter OverTemperature p. 392
Common causes
- Warning level of inverter heat sink temperature, warning level of chip junction temperature, or allowed change in temperature on chip junction is exceeded, resulting in pulse frequency reduction and/or output frequency reduction (depending on parameterization in P0290). p. 392
- Note: r0037 = 0: Heat sink temperature r0037 = 1: Chip junction temperature (includes heat sink) p. 392
- Check the following: p. 392
What to do
- - Ambient temperature must lie within specified limits - Load conditions and load steps must be appropriate - Fan must turn when drive is running p. 392
