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.

207012 <location>Drive: I2t motor model overtemperature
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The thermal I2t motor model identified that the temperature alarm threshold was exceeded.
See also: r0034 (Motor utilization), p0605 (Motor overtemperature 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)
207015 <location>Drive: Motor temperature sensor alarm
Message %1
value:
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 fault 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).

207016 <location>Drive: Motor temperature sensor fault
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF1 (NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
