Official Troubleshooting Steps
Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF2 (NONE, OFF1, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY SINAMICS-Alarms Cause: KTY: The motor temperature has exceeded the fault threshold (p0605) or the timer (p0606) after the alarm threshold was exceeded (p0604) has expired. The response parameterized in p0610 becomes active. PTC: The response threshold of 1650 Ohm was exceeded and the timer (p0606) has expired. The response parameterized in p0610 becomes active. Possible causes: - motor is overloaded. - motor ambient temperature too high. - wire breakage or sensor not connected. Fault value (r0949, interpret decimal): For SME selected (p0601 = 10), number of the sensor channel leading to the message. For I2t motor model activated (p0612 bit 0 = yes, p0611 > 0), fault value = 200 refers to a fault that was initiated by the I2t motor model. See also: p0604, p0605, p0606, p0610 Remedy: - reduce the motor load. - check the ambient temperature. - check the wiring and sensor connector. See also: p0604, p0605, p0606
