Component-level repair
Power stages, IGBT modules, DC-link capacitors, gate drivers, control & encoder PCBs, keypads and fans — failed parts replaced one by one until the drive is healthy, not blindly PCB-swapped.

What we do
Everything your 9300 needs, under one roof
Component-level repair is our core service — plus troubleshooting and parts, a single specialist for the drives the OEM stopped supporting.
Fault diagnosis & troubleshooting
OC, OH, UV and OV codes decoded. We analyse the history buffer and LECOM status words (C0150/C0155) to find the root cause — not just the symptom.
Send your fault codeParts & spares
Genuine Lenze and tested-compatible spares: IGBTs, capacitors, fans, brake resistors and brake modules (EMB9351-E), fieldbus and encoder PCBs.
Check availabilityRefurbished & exchange units
Tested refurbished EVS93xx units and a fast exchange program — keep your line running while yours is being repaired in our workshop.

The difference: PCB swap vs fixing the part
Most shops replace whole PCBs — expensive, and often no longer available for a 9300 that's out of production. We repair the failed component itself.
Whole-PCB swap
- ✕Replacement PCB cost can exceed the drive's value
- ✕9300 PCBs are out of production — stock shrinking, prices rising
- ✕The drive is declared "obsolete" and a new unit is recommended
Component-level repair
- ✓Only the failed parts are replaced — far lower cost
- ✓Your old 9300 stays alive — no need for a new unit
- ✓Full load-testing with motor & encoder, 6-month warranty
Our coverage
The whole 9300 family, fully covered
From the small EVS9321 to the 75 kW EVS9332 — if it says 9300 on the nameplate, we can repair it, troubleshoot it and supply parts for it.
- Servo, vector & standard — EVS93xx servo (ES/CS variants), 9300 vector and 9300 standard
- 0.37 … 75 kW — all frame sizes, 230 / 400 / 480 V mains versions
- Plug-in modules — fieldbus (PROFIBUS, CANopen, DeviceNet, INTERBUS), encoder and I/O PCBs
- Programming & data recovery — GDC, Drive PLC (EPL 10200) and parameter backup from dead units

-
02
Ship & diagnose
Send the drive in with your RMA number. Diagnosis is free — you only pay if you approve the repair.
-
03
Repair & test
Component-level repair, then full load-testing with motor and encoder — not just a bench light-up.
-
04
Return with warranty
Back on your line with a 6-month warranty and a report of what failed, why, and how to prevent it.
Client results
Trusted by plants that can't stop
“Our EVS9325-ES tripped with OC8 on a Friday afternoon. Machitron diagnosed it remotely the same day and had the drive back on our line by Wednesday — at half the cost of a new unit.”
“Three other shops said our 9300 vector was beyond repair. Machitron found a failed IGBT and a dry capacitor — repaired, load-tested and back in 5 days. 18 months later it's still running.”
“Lenze said our 1998 line was obsolete. Machitron supplied a tested refurbished EVS9329 with a 6-month warranty and recovered the parameters from the dead unit. We never stopped production.”
