官方故障排除步骤
Message value: Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The alarm threshold for the air intake overtemper ature has been reached. For air-cooled power units, the threshold is 42 °C (hysteresis 2 K). The response is set using p0290. If the air intake temperature increases by an additional 13 K, then fault F30035 is output. Remedy: Check the following: - is the ambient temperature wi thin the defined limit values? - has the fan failed? Check the direction of rotation.
