Diagnostic information
PROFIDrive classifies each alarm information of the servo drive. The specific category
information is shown in the following table:
Class
no.
Error class name Reason statement
1 Hardware or software malfunction A hardware or software fault occurs
2 Main power failure
The main power supply is faulty, with phase loss, overvoltage
and undervoltage
3 Control power failure Control power failure, 24V, 5V power supply is abnormal
4 Overvoltage of the DC bus DC bus voltage threshold above normal
5 Power electronic component failure
Power electronic component failure, such as overheating,
overcurrent or IGBT failure
6 Electronic component overheating Electronic component temperature exceeds normal threshold
7 Grounding, interphase short circuit
Grounding or interphase short circuit found in power cable or
motor winding
8 Motor overload
Motor over finite temperature, limit current or limit torque
operation
9
Communication failure of upper
controller
Between the drive and controller PROFINET communication
failure
10 Security monitoring channel failure Safety operation monitoring detects faults
11 Position feedback interface failure
Status error or signal loss occurs during encoder signal
processing
12 Internal communication failure
Drive internal communication between components abnormal
or interrupt
13 Power module failure Power supply module fault or failure
14 Brake module failure Internal or external brake module is abnormal or overheated
15 Power filter failure Power filter temperature too high or abnormal state
16 Abnormal external signal The external input signal exceeds the threshold or is abnormal
17
Failure of application and process
function
Driver monitoring position, speed, and torque over set
thresholds
18
Parameter setting or configuration
fails
Drive parameters are incorrectly configured or incorrectly
configured
19 Common Driver Faults Device component failure
20 Auxiliary device failure The monitoring of the auxiliary device is abnormal
