Official Troubleshooting Steps
Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: An error was detected when evaluating the temperature sensor set in p0600 and p0601. With the fault, the time in p0607 is started. If the faul t is still present after this time has expired, then fault F07016 is output; however, at the earliest, 1 s after alarm A07015. Possible causes: - wire breakage or sensor not connected (KTY: R > 1630 Ohm). - measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm). Alarm value (r2124, interpret decimal): For SME selected (p0601 = 10), number of the sensor channel leading to the message. Remedy: - check that the sensor is connected correctly. - check the parameterization (p0600, p0601). See also: r0035, p0600, p0601, p0607, p4600, p4601, p4602, p4603, r4620
