Code	Bezeichnung	Typischer Befund	Prüfung	Abhilfe
01	Undervoltage	Supply too low	Measure mains	Check voltage supply
02	Overcurrent	Short circuit in output or IPM	Check U/V/W	Check line / power section
03	Overvoltage	DC link voltage too high	Measure DC bus	Check mains voltage, connect brake resistor
05	Encoder error	No feedback signal	Check CN2	Replace encoder / cable
06	Overtemperature	Insufficient cooling flow	Check fan function	Clean or replace fan
07	Regeneration error	Feedback overloaded	Measure brake resistor	Increase capacity
09	Memory error	EEPROM or CPU error	Reset / Diagnose	Replace control board
12	Control error	Internal processor error	Self-test	Replace amplifier
32	Overcurrent IPM	Short circuit / transistor damage	Insulation measurement	Replace power section
35	Communication error	CNC data exchange disrupted	Check CN1	Check control cable / interface
45	Motor overtemperature	Thermal sensor in the motor active	Check temperature	Improve cooling
50	Overload	Permanent overcurrent load	Measure current profile	Check mechanics, adjust parameters
55	Absolute value error	Zero point data lost	Check encoder	Perform reference run

Input check: Visual inspection, voltage measurement, check for burn marks, loose connectors and thermal damage
Disassembly & cleaning: Removal of the power and control section, thorough cleaning, renewal of thermal conductive materials
Analysis: Testing of power section, driver circuits, capacitors, communication interface and temperature monitoring
Repair: Replacement of defective IGBTs, gate drivers, relays and connectors, rework of thermal zones
Testing & load test: Functional test with reference motor under rated current, monitoring of temperatures, voltage and current curves
Endurance test & completion: Continuous operation under load for several hours, complete documentation of the measurement results and creation of the test report
