Overtemp.device i2t: The parameter indicates how frequently event 39:Overtemp.device i2t
has occurred.
Event description:
Trigger: The i
2
t model for the inverter exceeds 100% of the thermal load.
Cause:  Inverter overloaded (e.g., because motor blocked).
 Too high clock pulse frequency.
Level: Inactive, message, warning or fault, can be parameterized in U02 (Default: fault).
Other: When the event is triggered, a current limitation occurs initially for control types
servo and vector control. At the same time, a quick stop is triggered as a fault
when parameterized in U02. Reduction of the current may mean that the quick
stop is no longer executed correctly!

Invalid data: The parameter indicates how frequently event 40:Invalid data has occurred.
Event description:
Trigger: A data error was detected when the non-volatile memory was initialized.
Cause: 1 to 7: Control unit memory
1: Fault; low-level read/write error or timeout.
2: BlockMiss; unknown data block.
3: DatSecur; block has no data security.
4: Checksum; block has checksum error.
5: R/o; block is r/o.
6: ReadErr; startup phase: block read error.
7: BlockMiss; block not found .
17 to 23: power unit memory
17: Fault; low-level read/write error or timeout.
18: BlockMiss; unknown data block.
19: DatSecur; block has no data security.
20: Checksum; block has checksum error.
21: R/o; block is r/o.
22: ReadErr; startup phase: block read error.
23: BlockMiss; block not found.
32 and 33: encoder memory
32: el. mot-type; no nameplate data present.
33: el.typeLim; elecronic motor-type limit; nameplate parameters cannot be
entered.
48: Optionmodule2; error in memory of option 2 with REA 5000 and XEA 5000
and XEA 5001 respectively.
Level: Fault
Acknowledgment: The event cannot be acknowledged for cause 1 to 23 and 48.
The inverter must be sent in for repairs. The event can be acknowledged for causes 32 and 33.

Temp.MotorTMP: The parameter indicates how frequently event 41:Temp.MotorTMP has
occurred.
Event description:
Trigger: Motor temperature sensor reports excess temperature. (Connection terminals
X2.3, X2.4).
Cause:  The motor is overloaded.
 The temperature sensor is not connected.
Level: Fault
Acknowledgment: Turn device off/on or programmed acknowledgment.

TempBrakeRes: The parameter indicates how frequently event 42:TempBrakeRes has
occurred.
Event description:
Trigger: The i
2
t model for the brake resistor exceeds 100% of the load.
Cause: • The brake resistor may not be adequate for the application.
Level: Fault
Acknowledgment: Programmed acknowledgment. Acknowledgment by turning the device off/on is
not recommended since the i
2
t model would be reset to 80% in this case and
there is a danger of the deceleration resistor being damaged.
