Your unit will be completely overhauled. The following work will be performed on this drive module:
- Replacement of worn and defective parts such as capacitors, transistor modules, ICs and resistors.
- Overhaul and testing of all levels e.g. driver amplifier control, transistor module control, communication levels and network modules.
- The drive module will be tested on the engine test system with an original engine for a prolonged period of time.
- Thorough cleaning: where required, the old paint will be removed and the relevant surface will be repainted.
The high quality work enables us to provide 12 months warranty for proper functioning.
We know about the following faults, for example, and can remedy them:
| Fault |
Cause |
| No function or LED display |
Power supply module, power supply module control, internal short circuit |
| The engine stutters |
Driver amplifier control, transistor modules failed |
| Only functions after warming up |
Internal power supply unit, system control board |
| No communication with the CNC |
System control board |
In principle, any possible faults can be detected and remedied in our test system.
