Faults and alarms
List of faults and alarms
F07011 Drive: Motor overtemperature
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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 exceeded (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, decimal interpretation):
200: The I2t motor model signals an overtemperature (p0612.0 = 1, p0611 > 0).
Number of the temperature channel leading to the message (for SME/TM120 (p0601 = 10, 11)).
See also: p0604 (Motor temperature alarm threshold), p0605 (Motor temperature fault threshold), p0606 (Motor tem-
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.

perature timer)
A07012 (N) Drive: I2t motor model overtemperature
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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)
Reaction upon N: NONE
Acknowl. upon N: NONE
A07015 Drive: Motor temperature sensor alarm
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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, 50 ms 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):
- if SME/TM120 is selected (p0601 = 10, 11),
this is the number of the temperature channel leading to the message.
