FaultCode

Fault ClassName

Comments

01

MicrocontrollerHardware orSoftware

Comprises exceptions in the main CPU of the drive, memory/checksum errors,over-/underrun in control processes, controller self test failed, etc.

02

Mains Supply

Comprises exceptions out of the mains supply like phase error, mains over-/untervoltage, etc.

03

Low VoltageSupply

Comprises exceptions out of the low voltage supply supplied to the drive system (e.g. external 24 V supply).

04

DC Link

Overvoltage

Exception because of overvoltage of the DC link, which typically is a result of

excessive energy feedback from the motor/process or a faulty dummy load.

05

PowerElectronics

Comprises exceptions in the inverter stage of the drive: phase current measurement errors, overcurrent supervision error.

06

OvertemperatureElectronicDevice

Overtemperature because of overload or faulty cooling system.

07

Isolation Fault

Exception because of over-current resulting from shortage between phase and phase or phase and ground.

08

Motor Overload

Exception because of over-temperature of the motor. This may be a result from motor overload or a faulty cooling system.

09

Fieldbus System

Exception from the Communication System between the drive (DU) and the controller. For example, this may be temporary communication frame errors or exceptions in the isochronous operation.

10

Safety Channel

Exception because of a fault in the drive safety function (e.g. results from the redundant safety paths don’t match).

11

Feedback

Exception because of an exception in the feedback interface or the feedback sensor (e.g. encoder, position or velocity measurement system).

12

InternalCommunication

Exception from the drive internal Communication System if there is a separate physical entity related to the internal Communication System (e.g. communication backplane, bus cable, etc.).

13

Infeed

Comprises exceptions out of the infeed unit of the drive: for example missing DC link voltage, etc.

14

Brake Resistor

Exception from the dummy load circuit of the drive: Over-temperature brake resistor, brake resistor no current, etc.

15

Line Filter

Exception from the main line filter in front of the infeed unit if the filter is a separate physical entity (e.g. over-temperature, etc.).

16

External

Exception posted by additional input channels to the drive. For example, a separate custom specific temperature sensor connected to the drive system by an digital input.

17

Technology

Exception from a drive internal process supervision task/system. For example, supervision of a torque limit.

18

Engineering

Exception from differences between real and expected configuration information.

19

Other

Necessary because every entry in the actual fault situation of the fault buffer and the warning mechanism shall result in an exception in one of the PROFIdrive fault classes because of consistency. Therefore, if a drive exception does not match with one of the defined fault classes it shall be mapped with the fault class (Other).

20

Auxiliary Device

Exception because of a fault in an auxiliary device of the drive which cannot be mapped to another fault class (e.g. special cooling devices often used for large drives).
