4 Faults and alarms
4.2 List of faults and alarms
For inverters, the following applies:
If the new power unit is accepted, then if required, the current limit (p0640) can be reduced by a lower maximum
current of the power unit (r0209) (torque limits stay the same).
If not only the power unit is changed, but also the motor, then the motor must be re-commissioned (e.g. using p0010
= 1). This is also necessary if motor data is still to be downloaded via DRIVE-CLiQ.

A07820 Drive: Temperature sensor not connected
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None
Reaction: NONE
Acknowledge: NONE
Cause: The temperature sensor for monitoring the motor temperature, specified in p0600, is not available.
Alarm value (r2124, interpret decimal):
1: p0601 = 10 (SME), but in p0600 - not evaluated via encoder is selected.
2: p0600 = 10 (BICO), but the signal source (p0603) is not interconnected.
3: p0601 = 11 (BICO), but in p0600 - not evaluated via BICO interconnection is selected (20 or 21).
4: p0601 = 11 (BICO) and p4610-p4613 > 0, but the associated signal source (p0608, p0609) is not interconnected.
5: Component with sensor evaluation not present or has been removed in the meantime.
6: Evaluation via Motor Module not possible (r0192.21).
Remedy: For alarm value = 1:
- in p0600 set an encoder with temperature sensor.
For alarm value = 2:
- interconnect p0603 with the temperature signal.
For alarm value = 3, 4:
- set the available temperature sensor (p0600, p0601).
- set p4610 ... p4613 = 0 (no sensor), or interconnect p0608 or p0609 with an external temperature signal.
For alarm value = 5:
- connect the component with the temperature sensor. Check the DRIVE-CLiQ connection.
For alarm value = 6:
- update the Motor Module firmware. Connect temperature sensor via encoder.

A07821 Monitoring underspeed threshold fallen below alarm
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: Control Unit (CU)
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for the lower speed was fallen below.
Note:
- the monitoring is activated using p2149.6 = 1.
- status bit r2197.1 = 1 indicates that the value has been fallen below.
- for closed-loop control without encoder, this alarm is only output for an excited motor (r0056.4 = 1); for closed-loop
control with encoder, it is always output.
- for a separately excited synchronous motor in closed-loop torque control without an encoder (p1300 = 20, p1501
set), the monitoring for an underspeed condition is automatically activated internally.
See also: p2140 (Hysteresis speed 2), p2149 (Monitoring configuration), p2155 (Speed threshold 2), r2197 (Status
word monitoring 1)
Remedy: - check the parameterization (p2155, p2140).
- if required, reduce the load.
- switch-on additional unit for generator applications.
