Drive: Motor Overtemperature; Drive: I2T Motor Model Overtemperature - Siemens Sinamics S120 Diagnostic Manual

207011 <location>Drive: Motor overtemperature
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0605) or the timer (p0606) after the alarm threshold was
exceeded (p0604) has expired.
PTC, bimetallic NC contact:
The response threshold of 1650 ohms was exceededd (in SME p4600..p4603 or in TM120 p4610..p4613 = 10 or 30),
or the timer (p0606) has expired after 1650 ohms was exceeded (in SME p4600..p4603 or in TM120 p4610..p4613 =
12 or 32).
Possible causes:
- motor is overloaded.
- motor ambient temperature too high.
- PTC / bimetallic NC contact: Wire breakage or sensor not connected.
Fault value (r0949, interpret decimal):
200: The I2t motor model (p0612.0 = 1, p0611 > 0) signals an overtemperature.
- if SME/TM120 is selected (p0601 = 10, 11),
this is the number of the temperature channel leading to the message.

perature timer)
Remedy: - reduce the motor load.
- check the ambient temperature and the motor ventilation.
- check the wiring and the connection of the PTC or bimetallic NC contact.

207012 <location>Drive: I2t motor model overtemperature
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: The thermal I2t motor model (for synchronous motors) identified that the temperature alarm threshold was exceeded.
See also: r0034 (Motor utilization), p0605 (Motor temperature fault threshold), p0611 (I2t motor model thermal time
constant)
Remedy: - check the motor load and if required, reduce.
- check the motor ambient temperature.
- check the thermal time constant p0611.
- check the overtemperature fault threshold p0605 (= alarm threshold for the I2t motor model, see p0612)
