r=3, w=3
Level overtemperature Device i2t: Parallel to the monitoring of the heat dissipater
temperature, an additional protective function is offered via i²t. The device load can be indicated as
a percentage via parameter E22. If the value in E22 is greater than 100%, U02 is triggered.
0: inactive; Device does not react to the triggering of U02.
1: Message; When U02 is triggered, this is only indicated. The device continues to remain ready for
operation.
2: Warning; After expiration of the tolerance time in U03, the device assumes fault status (for E39,
see chap. 17).
3: Fault
; After U02 is triggered, the device immediately assumes fault status (for E39, see chap.
17).

r=3, w=3
Time overtemperature Device i2t: Can only be set with U02=2:Warning. Defines the time
during which a trigger of the i²t monitoring is tolerated. After expiration of this time, the device
assumes fault status.
Value range in s: 1.00 ... 10,00 ... 60.00
Fieldbus: 1LSB=0,01s; Type: U8; (raw value:2 Bit=1·s); USS-Adr: 15 00 C0 00 hex

Level temperature motor i2t: Parallel to the monitoring of the positor line on the motor, the
inverter simulates the motor temperature via an i²t model. The motor load is indicated as a
percentage in parameter E23. If the value in E23 is greater than 100%, U10 is triggered.
0: inactive; Device does not react to the triggering of U10.
1: Message
; Triggering of U10 is only indicated. The device continues to be ready for operation.
2: Warning; After expiration of the tolerance time U11, the device assume fault status.

Time temperature motor i2t: Can only be set when U10=2:Warning. Defines the time during
which a trigger of i²t monitoring is tolerated. After expiration of this time, the device assumes fault
status.
Value range in s: 1.00 ... 30,00 ... 60.00
Fieldbus: 1LSB=0,01s; Type: U8; (raw value:2 Bit=1·s); USS-Adr: 15 02 C0 00 hex

Level motor connection: When the axis switch via POSISwitch
®
is utilized, the inverter can
test during switching whether the contactor of the motor to be switched off has actually broken
contact (opened). In addition, under certain circumstances, it can be determined that no motor is
connected.

Level MotorTMP: Trips when the motor temperature sensor on X2 triggers.
2: Warning; After expiration of the tolerance time U16, the device assume fault status.
