External fault 1: The parameter indicates how frequently event 44:External fault 1 has occurred.
Event description:
Trigger: Application specific or by free programming option.
Level: Fault
Acknowledgment: Turn device off/on or programmed acknowledgment.
Other: Should only be used for application events which may not be set lower than the
"fault" level.
Fieldbus: 1LSB=1; Type: U16; USS-Adr: 1A 0B 00 00 hex

Overtemp.motor i2t: The parameter indicates how frequently event 45:Overtemp.motor i2t has
occurred.
Event description:
Trigger: The i
2
t model for the motor has reached 100% of load.
Cause: • The motor is overloaded.
Level: Can be parameterized as inactive, message or warning in U10 and U11.
Acknowledgment: Turn device off/on or programmed acknowledgment.
Fieldbus: 1LSB=1; Type: U16; USS-Adr: 1A 0B 40 00 hex

Low voltage: The parameter indicates how frequently event 46:Low voltage has occurred.
Event description:
Trigger: The DC link voltage is lower than the limit value set in A35.
Cause: 1: Low Voltage; the value in E03 DC-link-voltage has dropped below the value
parameterized in A35 low voltage limit.
2: Network phase; phase monitoring has found that a switched-on power unit is
missing a phase.
3: Drop in network; when phase monitoring finds that the network voltage is
missing, the charging relay is immediately switched off. Normal operation is
maintained. If the power unit is still switched on after network voltage returns,
a fault is triggered after 0.5 s.
Level: Can be parameterized for cause 1 in U00 and U01. Warning with 10-second
warning time for cause 2, fault for cause 3.
Acknowledgment: Can be acknowledged for "fault" level by turning device off/on or programmed
acknowledgment.
Other: The motor always coasts down for cause 3.

Torque limit: The parameter indicates how frequently event 47:Torque limit has occurred.
Event description:
Trigger: The maximum torque permitted for static operation is exceeded for the control
types servo control, vector control or senorless vector control (E62:act. pos. M-
max, E66:act. neg. M-max).
Cause:  Limitation by parameters C03 and C05.
Level: Can be parameterized in U20 and U21.

Communication: The parameter indicates how frequently event 52:Communication has
occurred.
Event description:
Trigger: Communication fault
Cause: 1: CAN LifeGuard; recognized the "life-guarding-event" (master no
longer sends RTR).
2: CAN Sync Error; sync message was not received within the time set in
CANOpen object with index 1006 (cycle period timeout
3: CAN Bus Off; went off when bus went off.
The driver started it again.
4: PZD-Timeout; failure of the cyclic data connection (PROFIBUS).
5: USS; (under preparation) failure of the cyclic data connection (USS).
6: Systembus; (under preparation)
Level: Fault
Acknowledgment: Turn device off/on or programmed acknowledgment.
